| <div class="post__content"> |
| <p> |
| Apache Ignite was always appreciated by its users for two primary things it delivers - scalability and performance. Throughout the lifetime many distributed systems tend to do performance optimizations from a release to |
| release while making scalability related improvements just a couple of times. It's not because the scalability is of no interest. Usually, scalability requirements are set and solved once by a distributed system and |
| don't require significant additional interventions by engineers. |
| </p> |
| <p> |
| However, Apache Ignite grew to the point when the community decided to revisit its discovery subsystem that influences how well and far Ignite scales out. The goal was pretty clear - Ignite has to scale to 1000s of nodes |
| as good as it scales to 100s now. |
| </p> |
| <p> |
| It took many months to get the task implemented. So, please join me in welcoming Apache Ignite 2.5 that now can be scaled easily to 1000s of nodes and goes with other exciting capabilities. Let's check out the most |
| prominent ones. |

| Usually, Ignite community rolls out a new version once in 3 months, but we had to make an exception for Apache Ignite 2.4 that consumed five months in total. We could easily blame Thanksgiving, Christmas and New Year |
| holidays for the delay and would be forgiven, but, in fact, we were forging the release you can't simply pass by. |
| </p> |
| <p>Let's dive in and search for a big fish.</p> |
| <h3>Machine Learning General Availability</h3> |
| <p> |
| Eight months ago, at the time of Apache Ignite 2.0, we put out the first APIs that formed the foundation of the Ignite's machine learning component of today. Since that time, Ignite machine learning experts and |
| enthusiasts have been moving the liary to the general availability condition meticulously. And Ignite 2.4 became a milestone that let us consider the |
| <a href="https://apacheignite.readme.io/docs/machine-learning" target="_blank">ML Grid</a> to be production ready. |

| As promised in my <a href="https://blogs.apache.org/ignite/entry/protecting-apache-ignite-from-meltdown">initial blog post</a> on this matter, Apache Ignite community applied security patches against the |

| We finally made this happen! I’m happy to invite all of the software architects and engineers out there to a series of webinars that will introduce you to the fundamental capabilities of in-memory computing platforms |
| such as Apache Ignite. |
| </p> |
| <p>There will also be a mix of theory and practice. A lot of code examples are waiting to be shown so that you can apply the theory in practice right away.</p> |
| <p>The series consists of two parts.</p> |
| <h3><a href="https://ignite.apache.org/events.html#in-memory-computing-essentials-architects-and-developers-part-1" target="_blank">Part 1: Tuesday, November 21, 2017, 11:00am PT / 2:00pm ET</a></h3> |
| To be covered: |
| <ul> |
| <li>Cluster configuration and deployment.</li> |
| <li>Distributed database internals (partitioning, replication).</li> |
| <li>Data processing with key-value APIs.</li> |
| <li>Affinity Collocation.</li> |

| <p>Putting aside the regular bug fixes and performance optimizations, the Apache Ignite 2.3 release brings new SQL capabilities and Ignite persistence improvements that are worth mentioning.</p> |
| <p></p> |
| <h3>SQL</h3> |
| <p></p> |
| <p>Let's start with SQL first.</p> |
| <p>Apache Ignite users have consistently told us that despite all of Ignite’s SQL capabilities, it’s been at times challenging trying to figure out how to start using Ignite as an SQL database.</p> |
| <p> |
| This was mostly caused by scattered documentation pages, lack of “getting started” guides and tutorials. We’ve remedied this oversight! All related SQL knowledge has been curated in a |

| The power and beauty of in-memory computing projects are that they truly do what they state -- deliver outstanding performance improvements by moving data closer to the CPU, using RAM as a storage and spreading the data |
| sets out across a cluster of machines relying on horizontal scalability. |
| </p> |
| <p> |
| However, there is an unspoken side of the story. No matter how fast a platform is, we do not want to lose the data and encounter cluster restarts or other outages. To guarantee this we need to somehow make data persistent |
| on the disk. |
| </p> |
| <p> |
| Most in-memory computing projects address the persistence dilemma by giving a way to sync data back to a relational database (RDBMS). That sounds reasonable and undoubtedly works pretty well in practice, but if we dig |
| deeper, you’ll likely encounter the following limitations: |

| We released the long-awaited Apache Ignite version 2.0 on May 5. The community spent almost a year incorporating tremendous changes to the legacy Apache Ignite 1.x architecture. And all of that effort paid off. Our |
| collective blood, sweat (and perhaps even a few tears) opened up new and exciting opportunities for the Apache Ignite project. |
