----------------------------------------
Summary: Build multiple versions of the Flink Runner against
different Flink versions
Key: BEAM-5419
URL: https://issues.apache.org/jira/browse/BEAM-5419
Project: Beam
Issue Type: New Feature
Components: build-system, runner-flink
Reporter: Maximilian Michels
Assignee: Maximilian Michels
Fix For: 2.8.0
Following up on a discussion on the mailing list.
We want to keep the Flink version stable across different versions to avoid
upgrade pain for long-term users. At the same time, there are users out there
with newer Flink clusters and developers also want to utilize new Flink
features.
It would be great to build multiple versions of the Flink Runner against
different Flink versions.
When the upgrade is as simple as changing the version property in the build
script, this should be pretty straight-forward. If not, having a "base version"
and applying a patch during the build could be an option. We should avoid
duplicating any Runner code.
