    Good morning all! I just made a request to get my jira account set up, so if somebody could try and approve me I'll open a PR for this. I'm building out a Flink accelerator on top of DataFusion called [StreamFusion](github.com/datafusion-contrib/StreamFusion/tree/main). In order to do this, I'm hoping to add an extensible SQL planner api based on inspiration from what spark does (you specify a class in a runtime jar to add custom planning rules). The change is here if anybody has any initial feedback before I file an official merge request, thank you! github.com/jordepic/flink/commit/e0ca57a3b67f…

    The binding votes(JDBC connector v3.4.0) are still insufficient for this release. Could any PMC member please help review and cast a vote? Thanks! https://lists.apache.org/thread/dtps7w4hh7b2fc31rtd4cc7l2x0kt4pc

    Hey all, new to Flink coming from Apache Flume's dormancy, but we use OpenSearch 3 and was looking at the flink-connector-opensearch - but I am not seeing the OpenSearch3 builds yet in maven central. dumb question, is there a release pattern for the connectors or anyone have insights on when the OpenSearch3 connector would be released?

    Hi all, Raising this for discussion before pushing further on the linked PR. Problem: In the Flink CDC Iceberg pipeline connector, when an
    UPDATE
    changes the value of a partitioned column, the row ends up duplicated. The old partition retains a stale copy, while the new partition contains the updated row. The root cause is in `RowDataUtils#convertDataChangeEventToRowData`: every
    UPDATE
    is currently collapsed into a single after image row tagged as
    RowKind.INSERT
    , so no delete is emitted for the row's original partition. Since Iceberg equality deletes are partition scoped by design, the delete that gets written to the new partition cannot reach the stale row in the old partition. Compaction doesn't help either, since there is no delete marker for the stale row. This has been filed as FLINK-40640, with a proposed fix in PR #4536: split
    UPDATE
    handling into an explicit
    DELETE
    (before image) +
    INSERT
    (after image) pair, and have
    IcebergWriter
    write both. I've also added a regression test that reproduces the duplicate against the current main branch and passes with the change. No other tests are affected. This has also been running in our production CDC pipelines and has resolved the issue there without any regressions. One possible argument could be that this should be fixed on the Iceberg side. However, from what I understand, the issue is that Flink CDC is currently sending only an
    INSERT
    with the after image when running in upsert mode, which means the original row is never deleted. In that case, Iceberg cannot know that it needs to remove the row from the original partition. Also, recommending that users avoid having a column that can change as an Iceberg partition column doesn't seem like a practical workaround. There are many common business use cases where a frequently updated column can also be a meaningful partitioning column. Given the size and nature of the change, I wanted to check here first: does this require a FLIP, or would a Jira + PR + committer review be sufficient, given that this is a bug fix rather than a behavioral/design change? Also, if anyone is familiar with the Iceberg pipeline connector, could you please take a look at the PR? Thanks!

    Hi , if I have multiple jobs in operator mode there all and end up with the same context URL, so how can I configure context path for different different JOBS? So is there any reverse proxy available? We are using flink operator in openshift cluster It is community driven operator

    Hello committers/maintainers, This is a major bug that can cause duplicate data during Flink → Iceberg ingestion. The issue has already been fixed and merged, but the fix is currently available only in the 3.7.0-rc1 release. Would it be possible to backport this fix to the 3.6.x version as well? This could affect many users running the 3.6.x release. github.com/apache/flink-cdc/pull/4360
