| As of March 15, 2021, <a href="https://ignite.apache.org/">Apache Ignite</a> 2.10 has been released. You can directly check the full list of resolved <a href="https://s.apache.org/i3ny6">Important JIRA's</a> but here |
| let’s briefly overview some valuable improvements. |
| </p> |
| <h3 id="thin-clients">Thin Clients</h3> |
| Thin clients now support several important features which, previously were available only on the thick clients. Thin clients are always backward and forward compatible with the server nodes of the cluster, so the cluster |
| upgrade process will be more convenient if the lack of these features prevented you from doing that. |
| <p>See the list of what is changed for thin clients below:</p> |
| <ul> |
| <li>Transactions</li> |
| <li>Service invocations</li> |
| <li>Continuous Queries</li> |
| <li>SQL API</li> |
| <li>Cluster API</li> |
| <li>Cache Async API</li> |
| <li>Kubernetes Discovery (<em>ThinClientKubernetesAddressFinder</em>)</li> |
| </ul> |

| <div> |

| <p> |
| With thousands of changes contributed to Apache Ignite 2.8 that enhanced almost all the components of the platform, it’s possible to overlook some of the improvements that can convince you to upgrade to this version |
| sooner than later. While a quick check of the <a href="https://ignite.apache.org/releases/ignite2/2.8.0/release_notes.html" target="_blank">release notes</a> will help to discover anticipated bug fixes, this article aims |
| to guide through enhancements every Ignite developer should be aware of. |
| </p> |
| <h3>New Subsystem for Production Monitoring and Tracing</h3> |
| <p> |
| Several months of constant work on <a href="https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=112820392" target="_blank">IEP-35: Monitoring & Profiling</a> has resulted in the creation of a robust and |
| elastic subsystem for production monitoring and diagnostic (aka. profiling). This was influenced by the needs of many developers who deployed Ignite in critical environments and were asking for a foundation that can be |
| integrated with many external monitoring tools and be expanded easily. |
| </p> |
| <p> |
| The <a href="https://apacheignite.readme.io/docs/new-metrics#section-exporters" target="_blank">new subsystem</a> consists of several registries that group individual metrics related to a specific Ignite component. For |
| instance, you will find registries for cache, compute, or service grid APIs. Since the registries are designed to be generic, specific exporters can observe the state of Ignite via a myriad of tools supporting various |
| protocols. By default, Ignite 2.8 introduces exporters for monitoring interfaces such as log files, JMX and SQL views, and contemporary ones such as OpenCensus. |

| <div> |

| <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 |
| notorious Meltdown Spectre vulnerabilities and completed performance testing of general operations and workloads that are typical for Ignite deployments. |
| </p> |
| <p> |
| The security patches were applied only for <a href="https://nvd.nist.gov/vuln/detail/CVE-2017-5754" target="_blank">CVE-2017-5754</a> (Meltdown) and <a |

| <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 |
| <a href="https://apacheignite-sql.readme.io/docs" target="_blank">single documentation domain</a>. |
