Dear community, happy to share - a brief - community update this week with an update on Flink 1.10.1, our application to Google Season of Docs 2020, a discussion to support Hadoop 3, a recap of Flink Forward Virtual 2020 and a bit more.
Flink Development ============== * [releases] Yu has published a RC #2 for Flink 1.10.1. No -1s so far. [1] * [docs] Apache Flink's application to Google Season of Docs 2020 is about to be finalized. Marta has opened PR for the announcement and Seth & Aljoscha volunteered as Mentor. Apache Flink is pitching a project to improve the documentation of Table API & SQL. [2] * [hadoop] Robert has started a discussion on adding support for Hadoop 3. In particular, the thread discusses the questions of whether Hadoop 3 would be supported via flink-shaded-hadoop or not. [3] * [configuration] Timo has started a discussion on how we represent configuration hierarchies in properties (Flink configuration as well as Connector properties), so that the resulting files would be valid JSON/YAML. [4] * [connectors] Leonard Xu proposes to refactor package, module and class names of the Flink JDBC connector to be consistent with other connectors . Details in the [5].

[6] This statebackend is contributed to Apache in FLINK-12692 [7]. The SpillableHeapStateBackend is a Java Heap-based Statebackend (like the FilesystemStatebackend) that spills the coldest state to disk before the heap is exhausted. [6] https://flink-packages.org/packages/spillable-state-backend-for-flink [7] https://issues.apache.org/jira/browse/FLINK-12692 Notable Bugs ========== I did not encounter anything particularly worth sharing. Events, Blog Posts, Misc =================== * Fabian has published a recap of Flink Foward Virtual 2020 on the Ververica blog. [8] * All recordings of Flink Forward Virtual 2020 have been published on Youtube.
