| <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" markdown="1"> |
| <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 `OptionsFactory` and `ConfigurableOptionsFactory` classes are removed (not applicable for release-1.10), please use `RocksDBOptionsFactory` and `ConfigurableRocksDBOptionsFactory` instead. Please also recompile your application codes if any class extending `DefaultConfigurableOptionsFactory` |

| <div class="alert alert-info" markdown="1"> |
| <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 `setTotalOrderSeek` to true for RocksDB's `ReadOptions`, to prevent user from miss using `optimizeForPointLookup`. Meantime we support customizing `ReadOptions` through `RocksDBOptionsFactory`. Please set `setTotalOrderSeek` back to false if any performance regression observed (normally won't happen according to our testing). |
