Dear community,
happy to share an update for the last two weeks with the release of Apache Flink 1.11.1, planning for Flink 1.12, a proposal for better interoperability with Microsoft Azure services, a few blog posts and more. Flink Development ============== * [releases] Flink 1.11.1 was released as a quick follow up to the Flink 1.11.0 release mostly fixing some critical issues in the Table API/SQL ecosystem. [1] * [releases] Robert started a thread to collect the different topics/features that are planned for Flink 1.12. Robert & Dian will be our release managers for this one. They propose a feature freeze around the end of September. [2] * [connectors] Israel Ekpo started a thread to discuss the contribution of multiple connectors for Microsoft Azure services including Data Lake Store Gen 2 (Filesystem), Azure Cosmos DB (DataStream) and Azure Event Hub (DataStream). [3] * [sql] Seth has started a small discussion on how to handle timestamps if a "datagen" table is created based on an existing table using the LIKE clause. [4] * [connectors] Benchao raised the point that the semantic of InputFormat#nextRecord returning null is inconsistent throughout the code case and would like to align these. No feedback so far. [5] * [development process] Andrey reminds everyone to assign the "starter" label to Jira issues, which are a good pick for new contributors to Apache Flink. [6] Notable Bugs ========== * [FLINK-18705] [FLINK-18700] [1.11.1] For those of you, who are trying out the new Debezium format, check out the limitations reported in [7,8]. * [FLINK-18656] [1.11.1] The checkpoint start delay metric is always zero when unaligned checkpoints are used. [9] =================== * Two new posts on the Flink blog: * Dawid gives an overview over (external) catalogs (e.g. HiveMetastore, PostgreSQL) in Flink. [10] * Kostas introduces the newly added "Application Mode" and contrasts it to the two existing modes: "Session Mode" & "Per-Job Mode". [11] * In this blog post Eric J. Bruno of Dell explains in detail how Apache Flink can be used for complex event processing and streaming analytics. [12] * On the 23rd, the Apache Flink meetup group in Seoul hosted a virtual session with talks by SK Telecom (Korean), HyperConnect (Korean) and Ververica (English). It is available on Youtube [13]. * We have published the training program for Flink Forward Global taking place on the 20th & 21st of October. [14] There will be six different courses offered over these two days: * Flink Development (2 days) * SQL Development (2 days) * Runtime & Operations (1 day) * Stateful Functions (1 day) * Tuning & Troubleshooting (introduction and advanced, 1 day each). Cheers, Konstantin |
