| <h1>Apache Flink 1.10.2 Released</h1> |
| <p><i></i></p> |
| |
| <article> |
| <p>25 Aug 2020 Zhu Zhu (<a href="https://twitter.com/zhuzhv">@zhuzhv</a>)</p> |
| |
| <p>The Apache Flink community released the second bugfix version of the Apache Flink 1.10 series.</p> |
| |
| <p>This release includes 73 fixes and minor improvements for Flink 1.10.1. The list below includes a detailed list of all fixes and improvements.</p> |
| |
| <p>We highly recommend all users to upgrade to Flink 1.10.2.</p> |
| |
| <div class="alert alert-info"> |
| <p><span class="label label-info" style="display: inline-block"><span class="glyphicon glyphicon-info-sign" aria-hidden="true"></span> Note</span> |
| After FLINK-18242, the deprecated <code>OptionsFactory</code> and <code>ConfigurableOptionsFactory</code> classes are removed (not applicable for release-1.10), please use <code>RocksDBOptionsFactory</code> and <code>ConfigurableRocksDBOptionsFactory</code> instead. Please also recompile your application codes if any class extending <code>DefaultConfigurableOptionsFactory</code></p> |
| </div> |
| |
| <div class="alert alert-info"> |
| <p><span class="label label-info" style="display: inline-block"><span class="glyphicon glyphicon-info-sign" aria-hidden="true"></span> Note</span> |
| After FLINK-17800 by default we will set <code>setTotalOrderSeek</code> to true for RocksDB’s <code>ReadOptions</code>, to prevent user from miss using <code>optimizeForPointLookup</code>. Meantime we support customizing <code>ReadOptions</code> through <code>RocksDBOptionsFactory</code>. Please set <code>setTotalOrderSeek</code> back to false if any performance regression observed (normally won’t happen according to our testing).</p> |
