- <p>
- Apache Ignite as many other NoSQL databases is horizontally scalable, highly available and
- fault-tolerant. Ignite acts as a distributed partitioned hash map making sure that every cluster
- node owns a portion of the overall data set. This way the more cluster nodes you add, the more data
- you can store in the cluster.
- </p>
- <p>
- Ignite can either partition or replicate the data. Unlike <code>REPLICATED</code> mode, where data is
- fully replicated across all nodes in the cluster, in <code>PARTITIONED</code> mode Ignite will
- equally split the data across multiple cluster nodes, allowing for storing TBs of data both in
- <i>memory</i> and on <i>disk</i>.

- <p>
- Unlike eventually consistent NoSQL databases, Ignite can operate in a <i>strongly consistent</i> mode,
- guaranteeing the data consistency across all cluster nodes. In addition, ignte supports
- <a href="https://apacheignite.readme.io/docs/transactions">ACID transactions</a> that can span
- multiple keys acrsoss multiple cluster ndoes and partitions.
- </p>
-
- <p>
- The other difference between Ignite and NoSQL databases is that, first, the memory is
- treated as a fully functional storage, not just as a caching layer, like most databases do. Second,
- in addition to
- <a href="/features/datagrid.html">key-value</a> APIs, Ignite supports
- <a href="/features/sql.html">distributed SQL</a> and
- <a href="/features/collocatedprocessing.html">collocated processing</a> approach.

- <div style="padding:0 0 20px 0;">
- <p>
- Apache Ignite does not require you as a skilled RDBMS user to learn new APIs if you want to
- start working with an Ignite cluster. All the data processing and SQL schema definition can
- be accomplished with a familiar SQL syntax. Ignite complies with SQL ANSI-99 standard supporting all
- <b>SQL</b> and <b>DML</b> commands, including SELECT, UPDATE, INSERT, MERGE, DELETE statements and
- distributed joins. It also provides support for a subset of <b>DDL</b> commands relevant for
- distributed SQL databases.
- </p>
- <p>
- Ignite can store data and indexes both in memory and on disk which allows executing distributed SQL
- queries across different memory layers achieving the performance and scale of in-memory computing
- together with the disk durability and strong consistency in one system. If the persistence is disabled,
- Ignite can act as a pure <a href="/use-cases/database/in-memory-database.html">
- in-memory database</a>.

- The main difference between Ignite and traditional relational databases is that, first, the memory is
- treated as a fully functional storage, not just as a caching layer, like most databases do. Second,
- Ignite is horizontally scalable, highly available and supports both
- <a href="/features/datagrid.html">key-value</a> APIs and
- <a href="/features/collocatedprocessing.html">collocated processing</a> approach.
- </p>

- Check <a href="/features/sql.html">SQL</a> section for more details or start using
- Ignite as a SQL database referring to

+ <div class="col-sm-6 col-md-6 col-xs-12" style="padding-left:0; padding-right:0">
+ <p>
+ A digital integration hub (DIH) is an advanced platform architecture that aggregates
+ multiple back-end systems and databases into a low-latency and shared data store. Apache
+ Ignite can function as this high-performance shared store by caching and persisting data sets
+ dispersed across many disjointed external databases and systems.
+ </p>
+
+ <p>
+ Applications typically access Ignite via an API services layer and get substantial
+ performance growth by requesting data from this only distributed store that, in its turn,
+ keeps all the records in memory and offloads the back-end systems.
+ </p>
+ </div>
+
+ <div class="col-sm-6 col-md-6 col-xs-12" style="padding-right:0">
+ <img class="img-responsive" src="/images/digital-hub.png" width="440px"
+ style="float:right;"/>
+ </div>
+ </div>
+
+ <p>
+ The primary purpose of Ignite as of a DIH component is to enable implementations of large-scale and
+ high-throughput architectures that prevent the back-end systems from being overwhelmed with excessive
+ workloads and to avoid complex integrations between the back-end databases and front-end API services.
+ </p>
+
+ <div class="page-heading">Synchronization of Apache Ignite and Back-End Systems</div>
+ <p>
+ Ignite, as the high-performance data store, needs to be synchronized with the back-end databases via
+ streaming, event-based, change data capture (CDC), or other techniques.
+ </p>
+
+ <p>
+ Ignite provides a <code>CacheStore</code> interface for one-way synchronization between an Ignite
+ cluster and an external store supporting relational databases and some NoSQL stores out-of-the-box.
+ The interface allows Ignite to write-through or write-behind all the changes to the backend-systems
+ automatically. It also includes transactions - Ignite coordinates and commits a transaction across its
+ in-memory cluster as well as an external transactional database.
+ </p>
+
+ <p>
+ For bi-directional synchronization, you can consider various streaming, CDC, and event-based
+ technologies. For instance, Kafka, Spark, Debezium are widely used to keep Ignite in sync with other
+ databases.
+ </p>
+
+ <div class="page-heading">Real-Time Analytics</div>
+
+ <p>
+ Although real-time analytics is not a defining characteristic of digital integration hub architectures,
+ in some situations, you can end up consolidating operational and analytical data silos in Apache Ignite.
+ If this happens, you can tap into Ignite SQL, compute and machine learning capabilities for real-time
+ analytics needs.

- The Ignite In-Memory Data Fabric provides a unified API that spans
- JVM-based languages like Java, Scala and Groovy as well as first class support for
- Microsoft CLR (.NET/C#) and C++. It connects them with multiple data stores containing structured,
- semi-structured and unstructured data (SQL, NoSQL, Hadoop). It offers a secure, highly available and
- manageable data environment that allows to process full ACID transactions and generate
- valuable insights from real-time, interactive and batch queries.
- </p>
-
- <p>
- Ignites's In-Memory Data Fabric for .NET is designed to deliver uncompromised
- performance for a wide set of in-memory computing use cases on top of .NET platform -
- from high performance computing, to the industry most advanced data grid, CEP, and data streaming - all through native, optimized .NET APIs.

-
- <p>
- One of the key technology behind .NET In-Memory Data Fabric is Portable Object that allows Ignite code access and exchange objects between multiple platforms:
- <ul class="page-list">
- <li>Seamlessly interoperate between Java and .NET.</li>
- <li>Make any object portable with zero code change to your existing code.</li>
- <li>Nest portable objects within each other.</li>
- <li>Automatically handle circular or null references.</li>
- <li>Automatically convert collections and maps between Java, .NET, and C++.</li>
- <li>Optionally avoid deserialization of objects on the server side.</li>
- <li>Avoid need to have concrete class definitions on the server side.</li>
- <li>Dynamically change structure of the classes without having to restart the cluster.</li>
- <li>Index into portable objects for querying purposes.</li>
- </ul>
