+Apache Wayang is an effort undergoing incubation at The Apache Software
+Foundation (ASF), sponsored by the Apache Incubator PMC. Incubation is required
+of all newly accepted projects until a further review indicates that the
+infrastructure, communications, and decision making process have stabilized in
+a manner consistent with other successful ASF projects. While incubation status
+is not necessarily a reflection of the completeness or stability of the code,
+it does indicate that the project has yet to be fully endorsed by the ASF.

+ <p>Apache Wayang has a three-layer data processing abstraction that sits between user applications and data processing platforms, such as Hadoop and Spark. The figure below depicts the Apache Wayang architecture: (i) an application layer that models all application-specific logic; (ii) a core layer that provides the intermediate representation between applications and processing platforms; and (iii) a platform layer that embraces the underlying processing platforms. Overall, the input of an application layer comprises the logical operators provided by users (or generated by a declarative query parser) and the output is a physical plan (WayangPlan). The WayangPlan is then passed to the core layer where cross-platform optimizations take place to produce an execution plan (ExecutionPlan).<br /><br /> Notice that, in contrast to DBMSs, Apache Wayang decouples physical and execution levels. This separation allows applications to express physical plans in terms of algorithmic needs only, without being tied to a particular processing platform. The salient features of Apache Wayang are cross-platform task execution, high-performance, flexibility, and ease-of-use.</p>

+ The most salient feature of Apache Wayang is its cross-platform optimizer. Besides deciding the best processing platform to run any incoming task, Apache Wayang can run a single task on multiple processing platforms. Overall, it applies an extensible set of graph transformations to a Apache Wayang plan to find alternative execution plans. Then, it compares all execution plans by using a platform-specific cost model. Cost functions can either be given or learned, and are parameterized with respect to the underlying hardware (e.g., number of computing nodes for distributed operators).

+ Apache Wayang provides a number of optimized operators and novel query optimization process that allows it to efficiently deal with big (as well as small) datasets. Furthermore, as its data processing abstraction is based on UDFs, Apache Wayang lets applications expose semantic properties about their functions, optimization hints (e.g., numbers of iterations), constraints (e.g., physical collocation of operators), and alternative plans. The optimizer then uses those artifacts where available in a best-effort approach.

+ Apache Wayang provides a set of Wayang operators, which applications use to specify their tasks, as well as a set of execution operators, which processing platform provide to run application tasks. The key aspect is that Apache Wayang provides a flexible operator mapping structure allowing developers to add, modify, or delete mappings among Wayang and execution operators. As a result, developers can also add or remove Wayang and execution operators.

+ Apache Wayang exposes a simple Java API to developers whereby they can implement their tasks. Developers focus on the logics of their tasks rather than on low-level details specific to data processing platforms. The figure of the SGD plans above shows the Wayang plan for a scalable gradient descent implementation: we clearly see that this tedious implementation task is now much easier!

+ Apache Wayang is an effort undergoing Incubation at The Apache Software Foundation (ASF), sponsored by the Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

+ Apache Wayang is an effort undergoing Incubation at The Apache Software Foundation (ASF), sponsored by the Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

+ <p>In contrast to classical data processing systems that provide one dedicated execution engine, Apache Wayang rather is a <em>meta processing framework</em>: You can specify your data processing app via one of Apache Wayang’s API and then Apache Wayang will pick an optimal configuration of classical processing frameworks, such as Java Streams or Apache Spark, to run your app on. Finally, Apache Wayang will also perform the execution, thereby hiding the different specific platform APIs and coordinate inter-platform communication.</p>
+
+<p>This approach aims at freeing data engineers and software developers from the burden of knowing the zoo of different data processing systems, their APIs, strengths and weakness; the intricacies of coordinating and integrating different processing platforms; and the inflexibility when tying to a fix set of processing platforms. As of now, Apache Wayang has built in support for the following processing platforms:</p>
+
+<ul>
+ <li>Java 8 Streams</li>
+ <li><a href="https://spark.apache.org/">Apache Spark</a></li>
+ <li><a href="https://github.com/GraphChi/graphchi-java">GraphChi</a></li>
+ <li><a href="http://www.postgresql.org">Postgres</a></li>
+ <li><a href="https://www.sqlite.org/">SQLite</a></li>
+</ul>
+
+<h2 id="how-to-use-apache-wayang">How to use Apache Wayang</h2>
+
+<h3 id="requirements">Requirements:</h3>
+
+<p>Apache Wayang is built with Java 8 and Scala 2.11. However, to execute Apache Wayang it is sufficient to have Java 8 installed. If you want to build Apache Wayang yourself, you will also need to have <a href="http://maven.apache.org">Apache Maven</a> installed. Please also consider that processing platforms employed by Apache Wayang might have further requirements.</p>
+
+<h3 id="get-apache-wayang">Get Apache Wayang:</h3>
+
+<p>Apache Wayang is available via Maven Central. To use it with Maven, for instance, include the following into you POM file:</p>
+
+<div class="language-xml highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nt"><dependency></span>
+ <span class="nt"><groupId></span>org.apache.wayang<span class="nt"></groupId></span>
+ <span class="nt"><artifactId></span>wayang-***<span class="nt"></artifactId></span>
+ <span class="nt"><version></span>0.3.0<span class="nt"></version></span>
+<span class="nt"></dependency></span>
+</code></pre></div></div>
+
+<p>Note the <code class="language-plaintext highlighter-rouge">***</code>: Apache Wayang ships with multiple modules that can be included in your app, depending on how you want to use it:</p>
+<ul>
+ <li><code class="language-plaintext highlighter-rouge">wayang-core</code>: provides core data structures and the optimizer (required)</li>
+ <li><code class="language-plaintext highlighter-rouge">wayang-basic</code>: provides common operators and data types for your apps (recommended)</li>
+ <li><code class="language-plaintext highlighter-rouge">wayang-api</code>: provides an easy-to-use Scala and Java API to assemble wayang plans (recommended)</li>
+ <li><code class="language-plaintext highlighter-rouge">wayang-java</code>, <code class="language-plaintext highlighter-rouge">wayang-spark</code>, <code class="language-plaintext highlighter-rouge">wayang-graphchi</code>, <code class="language-plaintext highlighter-rouge">wayang-sqlite3</code>, <code class="language-plaintext highlighter-rouge">wayang-postgres</code>: adapters for the various supported processing platforms</li>
+ <li><code class="language-plaintext highlighter-rouge">wayang-profiler</code>: provides functionality to learn operator and UDF cost functions from historical execution data</li>
+</ul>
+

+<p>If you need to rebuild Apache Wayang, e.g., to use a different Scala version, you can simply do so via Maven:</p>
+
+<ol>
+ <li>Adapt the version variables (e.g., <code class="language-plaintext highlighter-rouge">spark.version</code>) in the main <code class="language-plaintext highlighter-rouge">pom.xml</code> file.</li>
+ <li>Build Apache Wayang with the adapted versions.<code class="language-plaintext highlighter-rouge">$ mvn clean install</code>. <strong>Note</strong> the <code class="language-plaintext highlighter-rouge">standalone</code> profile to fix Hadoop and Spark versions, so that Apache Wayang apps do not explicitly need to declare the corresponding dependencies. Also, note the <code class="language-plaintext highlighter-rouge">distro</code> profile, which assembles a binary Apache Wayang distribution. To activate these profiles, you need to specify them when running maven, i.e.,<code class="language-plaintext highlighter-rouge">mvn clean install -P<profile name></code></li>

+
+<h3 id="code-with-apache-wayang">Code with Apache Wayang:</h3>
+
+<p>The recommended way to specify your apps with Apache Wayang is via its Scala or Java API from the <code class="language-plaintext highlighter-rouge">wayang-api</code> module. You can find examples below.</p>
+
+<h3 id="learn-cost-functions">Learn cost functions:</h3>
+
+<p>Apache Wayang provides a utility to learn cost functions from historical execution data. Specifically, Apache Wayang can learn configurations for load profile estimators (that estimate CPU load, disk load etc.) for both operators and UDFs, as long as the configuration provides a template for those estimators. As an example, the <code class="language-plaintext highlighter-rouge">JavaMapOperator</code> draws its load profile estimator configuration via the configuration key <code class="language-plaintext highlighter-rouge">wayang.java.map.load</code>. Now, it is possible to specify a load profile estimator template in the configuration under the key <code class="language-plaintext highlighter-rouge">&lt;original key&gt;.template</code>, e.g.:</p>
+
+<div class="language-json highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="err">wayang.java.map.load.template</span><span class="w"> </span><span class="err">=</span><span class="w"> </span><span class="p">{</span><span class="err">\</span><span class="w">
+ </span><span class="nl">"in"</span><span class="p">:</span><span class="mi">1</span><span class="p">,</span><span class="w"> </span><span class="nl">"out"</span><span class="p">:</span><span class="mi">1</span><span class="p">,</span><span class="err">\</span><span class="w">
+ </span><span class="nl">"cpu"</span><span class="p">:</span><span class="s2">"?*in0"</span><span class="err">\</span><span class="w">
+</span><span class="p">}</span><span class="w">
+</span></code></pre></div></div>
+
+<p>This template specifies a load profile estimator that expects (at least) one input cardinality and one output cardinality. Further, it models a CPU load that is proportional to the input cardinality. However, more complex functions are possible. In particular, you can use</p>
+
+<ul>
+ <li>the variables <code class="language-plaintext highlighter-rouge">in0</code>, <code class="language-plaintext highlighter-rouge">in1</code>, … and <code class="language-plaintext highlighter-rouge">out0</code>, <code class="language-plaintext highlighter-rouge">out1</code>, … to incorporate the input and output cardinalities, respectively;</li>
+ <li>operator properties, such as <code class="language-plaintext highlighter-rouge">numIterations</code> for the <code class="language-plaintext highlighter-rouge">PageRankOperator</code> implementations;</li>
+ <li>the operators <code class="language-plaintext highlighter-rouge">+</code>, <code class="language-plaintext highlighter-rouge">-</code>, <code class="language-plaintext highlighter-rouge">*</code>, <code class="language-plaintext highlighter-rouge">/</code>, <code class="language-plaintext highlighter-rouge">%</code>, <code class="language-plaintext highlighter-rouge">^</code>, and parantheses;</li>
+ <li>the functions <code class="language-plaintext highlighter-rouge">min(x0, x1, ...))</code>, <code class="language-plaintext highlighter-rouge">max(x0, x1, ...)</code>, <code class="language-plaintext highlighter-rouge">abs(x)</code>, <code class="language-plaintext highlighter-rouge">log(x, base)</code>, <code class="language-plaintext highlighter-rouge">ln(x)</code>, <code class="language-plaintext highlighter-rouge">ld(x)</code>;</li>
+ <li>and the constants <code class="language-plaintext highlighter-rouge">e</code> and <code class="language-plaintext highlighter-rouge">pi</code>.</li>
+</ul>
+
+<p>While Apache Wayang specifies templates for all execution operators, you will need to specify that your UDFs are modelled by some configuration-based cost function (see the k-means example below) and create the according initial specification and template yourself. Once, you gathered execution data, you can run</p>
+
+<div class="language-shell highlighter-rouge"><div class="highlight"><pre class="highlight"><code>java ... org.apache.wayang.profiler.ga.GeneticOptimizerApp <span class="o">[</span>configuration URL <span class="o">[</span>execution log]]
+</code></pre></div></div>
+
+<p>This app will try to find appropriate values for the question marks (<code class="language-plaintext highlighter-rouge">?</code>) in the load profile estimator templates to fit the gathered execution data and ready-made configuration entries for the load profile estimators. You can then copy them into your configuration.</p></p>

+ Apache Wayang is an effort undergoing Incubation at The Apache Software Foundation (ASF), sponsored by the Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

+ Apache Wayang is a system designed to fully support cross-platform data processing: It enables users to run data analytics over multiple data processing platforms. For this, it provides an abstraction on top of existing platforms in order to run data analytic tasks on top of any set of platforms. As a result, users can focus on the logics of their applications rather on the intricacies of the underlying platforms.

+ Apache Wayang is an effort undergoing Incubation at The Apache Software Foundation (ASF), sponsored by the Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

+ <hr />
+ <p>Data cleansing approaches have usually focused on detecting and fixing errors with little attention to scaling to big datasets. This presents a serious impediment since data cleansing often involves costly computations such as enumerating pairs of tuples, handling inequality joins, and dealing with user-defined functions. In this paper, we present BigDansing, a Big Data Cleansing system to tackle efficiency, scalability, and ease-of-use issues in data cleansing. The system can run on top of most common general purpose data processing platforms, ranging from DBMSs to MapReduce-like frameworks. A user-friendly programming interface allows users to express data quality rules both declaratively and procedurally, with no requirement of being aware of the underlying distributed platform. BigDansing takes these rules into a series of transformations that enable distributed computations and several optimizations, such as shared scans and specialized joins operators. Experimental results on both synthetic and real datasets show that BigDansing outperforms existing baseline systems up to more than two orders of magnitude without sacrificing the quality provided by the repair algorithms.</p>

+ <p>Inequality joins, which join relational tables on inequality conditions, are used in various applications. While there have been a wide range of optimization methods for joins in database systems, from algorithms such as sort-merge join and band join, to various indices such as B+-tree, R∗-tree and Bitmap, inequality joins have received little attention and queries containing such joins are usually very slow. In this paper, we introduce fast inequality join algorithms. We put columns to be joined in sorted arrays and we use permutation arrays to encode positions of tuples in one sorted array w.r.t. the other sorted array. In contrast to sort-merge join, we use space efficient bit-arrays that enable optimizations, such as Bloom filter indices, for fast computation of the join results. We have implemented a centralized version of these algorithms on top of PostgreSQL, and a distributed version on top of Spark SQL. We have compared against well known optimization techniques for inequality joins and show that our solution is more scalable and several orders of magnitude faster.</p>

+ <p>The world is fast moving towards a data-driven society where data is the most valuable asset. Organizations need to perform very diverse analytic tasks using various data processing platforms. In doing so, they face many challenges; chiefly, platform dependence, poor interoperability, and poor performance when using multiple platforms. We present RHEEM, our vision for big data analytics over diverse data processing platforms. RHEEM provides a threelayer data processing and storage abstraction to achieve both platform independence and interoperability across multiple platforms. In this paper, we discuss our vision as well as present multiple research challenges that we need to address to achieve it. As a case in point, we present a data cleaning application built using some of the ideas of RHEEM. We show how it achieves platform independence and the performance benefits of following such an approach.</p>

+ <p>Many emerging applications, from domains such as healthcare and oil & gas, require several data processing systems for complex analytics. This demo paper showcases Rheem, a framework that provides multi-platform task execution for such applications. It features a three-layer data processing abstraction and a new query optimization approach for multi-platform settings. We will demonstrate the strengths of Rheem by using real-world scenarios from three different applications, namely, machine learning, data cleaning, and data fusion.</p>

+ <hr />
+ <p>Bored of keep moving your app to the newest data processing platform to achieve high performance? Tired of dealing with a zoo of processing platforms to get the best performance for your analytic tasks? Then, this tutorial is for you!</p>
+
+<p>Indeed, we are witnessing a plethora of innovative data processing platforms in the last few years. While this is generally great, leveraging these new technologies in practice bears quite some challenges, just to name a few, developers must: (i) find among the plethora of processing platforms the best one for their applications; (ii) migrate their applications to newer and faster platforms every now and then; and (iii) orchestrate different platforms so that applications leverage their individual benefits.</p>
+
+<p>We address these issues with Rheem, a system that enables big data analytics over multiple data processing platforms in a seamless manner. It provides a three-layer data processing abstraction with that applications can achieve both platform independence and interoperability across multiple platforms. With Rheem, dRheemers (Rheem developers) can focus on the logics of their applications. Rheem, in turn, takes care of efficiently executing applications by choosing either a single or multiple processing platforms. To achieve this, it comes with a cross-platform optimizer that allows a single task to run faster over multiple platforms than on a single platform.</p>

+ <hr />
+ <p>Inequality joins, which is to join relations with inequality conditions, are used in various applications. Optimizing joins has been the subject of intensive research ranging from efficient join algorithms such as sort-merge join, to the use of efficient indices such as 𝐵+-tree, 𝑅∗-tree and Bitmap. However, inequality joins have received little attention and queries containing such joins are notably very slow. In this paper, we introduce fast inequality join algorithms based on sorted arrays and space-efficient bit-arrays. We further introduce a simple method to estimate the selectivity of inequality joins which is then used to optimize multiple predicate queries and multi-way joins. Moreover, we study an incremental inequality join algorithm to handle scenarios where data keeps changing. We have implemented a centralized version of these algorithms on top of PostgreSQL, a distributed version on top of Spark SQL, and an existing data cleaning system, NADEEF. By comparing our algorithms against well-known optimization techniques for inequality joins, we show our solution is more scalable and several orders of magnitude faster.</p>

+ <hr />
+ <p>As the use of machine learning (ML) permeates into diverse application domains, there is an urgent need to support a declarative framework for ML. Ideally, a user will specify an ML task in a high-level and easy-to-use language and the framework will invoke the appropriate algorithms and system configurations to execute it. An important observation towards designing such a framework is that many ML tasks can be expressed as mathematical optimization problems, which take a specific form. Furthermore, these optimization problems can be efficiently solved using variations of the gradient descent (GD) algorithm. Thus, to decouple a user specification of an ML task from its execution, a key component is a GD optimizer. We propose a cost-based GD optimizer that selects the best GD plan for a given ML task. To build our optimizer, we introduce a set of abstract operators for expressing GD algorithms and propose a novel approach to estimate the number of iterations a GD algorithm requires to converge. Extensive experiments on real and synthetic datasets show that our optimizer not only chooses the best GD plan but also allows for optimizations that achieve orders of magnitude performance speed-up.</p>

+ <hr />
+ <p>We are witnessing a proliferation of big data, which has lead to a zoo of data processing systems. Each system providing a different set of features. For example, Spark provides scalability to analytic tasks, but Java 8 Streams provides low-latency. Furthermore, complex applications, such as ETL and ML, are now requiring a mixture of platforms to perform tasks efficiently. In such complex data analytics pipelines, the use of multiple data processing system is not only for performance reasons, but also because of data diversity. Datasets often natively reside on different data formats and storage engines. Unfortunately, developers are left alone in the challenging tasks of: (1) choosing the right platform for their applications; and (2) performing tedious and costly data migration and integration tasks to obtain the results.</p>
+
+<p>In this talk, we will present Rheem, an open source scalable cross-platform system that frees developers from these burdens. Rheem provides an abstraction layer on top of Spark (and other processing platforms) with the aim of enabling cross-platform optimization and interoperability. It automatically selects the best data processing platforms for a given task and also handles the cross-platform execution. In particular, we will discuss how Rheem allows Spark to work in tandem with other platforms in order to achieve higher performance. We will also show how easy a developer can write complex applications on top of Rheem to seamlessly use multiple different data processing platforms according to their tasks at hand. Using Rheem developers do not have to worry about the integration or data migration between Spark and other platforms.</p>

+ <p>Many of today’s applications need several data processing platforms for complex analytics. Thus, recent systems have taken steps towards supporting cross-platform data analytics. Yet, current cross-platform systems lack of ease-of-use, which is crucial for their adoption. This demo presents RHEEMStudio, a visual IDE on top of RHEEM. It allows users to easily specify their cross-platform data analytic tasks. In this demo, we will demonstrate five main features of RHEEMStudio: drag-and-drop, declarative, interactive, and customized specification of data analytic tasks as well as easy monitoring of tasks. With this in mind, we will consider two real use cases, one from the machine learning world and the second one based on data discovery. During all the demo, the audience will be able to take part and create their own data analytic tasks too.</p>

+ <hr />
+ <p>There is a zoo of data processing platforms which help users and organizations to extract value out of their data. Although each of these platforms excels in specific aspects, users typically end up running their data analytics on suboptimal platforms. This is not only because choosing the right platform among the myriad of big data platforms is a daunting task, but also due to the fact that today’s data analytics are moving beyond the limits of a single platform. Thus, there is an urgent need for cross-platform data processing, i.e., using more than one data processing platform to perform a data analytics task. Despite the need, achieving this is still a dreadful process where developers have to get intimate with many systems and write ad hoc scripts for integrating them. This tutorial is motivated by this need. We will discuss the importance of supporting cross-platform data processing in a systematic way as well as the current efforts to achieve that. In particular, we will introduce a classification of the different cases where an application needs or benefits from cross-platform data processing and the challenges of each case. Along with this classification, we will also present the efforts known up to date to support cross-platform data processing. We will conclude this tutorial with a discussion of several important open problems.</p>

+ <hr />
+ <p>Solving business problems increasingly requires going beyond the limits of a single data processing platform (platform for short), such as Hadoop or a DBMS. As a result, organizations typically perform tedious and costly tasks to juggle their code and data across different platforms. Addressing this pain and achieving automatic cross-platform data processing is quite challenging: finding the most efficient platform for a given task requires quite good expertise for all the available platforms. We present Rheem, a general-purpose cross-platform data processing system that decouples applications from the underlying platforms. It not only determines the best platform to run an incoming task, but also splits the task into subtasks and assigns each subtask to a specific platform to minimize the overall cost (e.g., runtime or monetary cost). It features (i) an interface to easily compose data analytic tasks; (ii) a novel cost-based optimizer able to find the most efficient platform in almost all cases; and (iii) an executor to efficiently orchestrate tasks over different platforms. As a result, it allows users to focus on the business logic of their applications rather than on the mechanics of how to compose and execute them. Using different real-world applications with Rheem, we demonstrate how cross-platform data processing can accelerate performance by more than one order of magnitude compared to single-platform data processing.</p>

+ <p>Data analytics are moving beyond the limits of a single data processing platform. A cross-platform query optimizer is necessary to enable applications to run their tasks over multiple platforms efficiently and in a platform-agnostic manner. For the optimizer to be effective, it must consider data movement costs across different data processing platforms. In this paper,we present the graph-based data movement strategy used by RHEEM, our open-source cross-platform system. In particular, we(i) model the data movement problem as a new graph problem,which we prove to be NP-hard, and (ii) propose a novel graph exploration algorithm, which allows RHEEMto discover multiple hidden opportunities for cross-platform data processing</p>

+ <hr />
+ <p>Although big data processing has become dramatically easier over the last decade, there has not been matching progress over bigdata debugging. It is estimated that users spend more than 50% of their time debugging their big data applications, wasting machine resources and taking longer to reach valuable insights. One cannot simply transplant traditional debugging techniques to big data. In this paper, we propose the TagSniff model, which can dramatically simplify data debugging for dataflows (the de-facto programming model for big data). It is based on two primitives –tag and sniff– that are flexible and expressive enough to model all common bigdata debugging scenarios. We then presentSnoopy– a general purpose monitoring and debugging system based on the TagSniff model. It supports both online and post-hoc debugging modes.Our experimental evaluation shows that Snoopy incurs a very low over head on the main dataflow, 6%on average, as well as it is highly responsive to system events and users instructions.</p>

+ <hr />
+ <p>Cost-based optimization is widely known to suffer from a major weakness: administrators spend a significant amount of time to tune the associated cost models. This problem only gets exacerbated in cross-platform settings as there are many more parameters that need to be tuned. In the era of machine learning(ML), the first step to remedy this problem is to replace the cost model of the optimizer with an ML model. However, such a solution brings in two major challenges. First, the optimizer has to transform a query plan to a vector million times during plan enumeration incurring a very high overhead. Second, a lot of training data is required to effectively train the ML model.We overcome these challenges in Robopt, a novel vector-based optimizer we have built for Rheem, a cross-platform system. Robopt not only uses an ML model to prune the search space but also bases the entire plan enumeration on a set of algebraic operations that operate on vectors, which are a natural fit to the ML model. This leads to both speed-up and scale-up of the enumeration process by exploiting modern CPUs via vectorization. We also accompany Robopt with a scalable training data generator for building its ML model. Our evaluation shows that (i) the vector-based approach is more efficient and scalable than simply using an ML model and (ii) Robopt matches and, in some cases, improves Rheem’s cost-based optimizer in choosing good plans without requiring any tuning effort.Index Terms—query optimization, machine learning, cross-platform data processing, polystores.</p>

+ <hr />
+ <p>Data analytics are moving beyond the limits of a single platform. In this paper, we present the cost-based optimizer of Rheem, an open-source cross-platform system that copes with these new requirements. The optimizer allocates the subtasks of data analytic tasks to the most suitable platforms. Our main contributions are: (i) a mechanism based on graph transformations to explore alternative execution strategies; (ii) a novel graph-based approach to determine efficient data movement plans among subtasks and platforms; and (iii) an efficient plan enumeration algorithm, based on a novel enumeration algebra. We extensively evaluate our optimizer under diverse real tasks. We show that our optimizer can perform tasks more than one order of magnitude faster when using multiple platforms than when using a single platform</p>

+ <hr />
+ <p>We propose RL-Cargo, a revenue management approach for air-cargo that combines machine learning prediction with decision-making using deep reinforcement learning. This approach addresses a problem that is unique to the air-cargo business, namely the wide discrepancy between the quantity (weight or volume) that a shipper will book and the actual amount received at departure time by the airline. The discrepancy results in sub-optimal and inefficient behavior by both the shipper and the airline resulting in an overall loss of potential revenue for the airline. A DQN method using uncertainty bounds from prediction is proposed for decision making under a prescriptive learning framework. Parts of RL-Cargo have been deployed in the production environment of a large commercial airline company. We have validated the benefits of RL-Cargo using a real dataset. More specifically, we have carried out simulations seeded with real data to compare classical Dynamic Programming and Deep Reinforcement Learning techniques on offloading costs and revenue generation. Our results suggest that prescriptive learning which combines prediction with decision-making provides a principled approach for managing the air cargo revenue ecosystem. Furthermore, the proposed approach can be abstracted to many other application domains where decision making needs to be carried out in face of both data and behavioral uncertainty.</p>
