-------------------------------------
Summary: FLIP-198: Working directory for Flink processes
Key: FLINK-25402
URL: https://issues.apache.org/jira/browse/FLINK-25402
Project: Flink
Issue Type: New Feature
Components: Runtime / Coordination
Affects Versions: 1.15.0
Reporter: Till Rohrmann
Assignee: Till Rohrmann
Fix For: 1.15.0
This issue implements [FLIP-198|https://cwiki.apache.org/confluence/x/ZZiqCw].
The idea is to introduce a working directory that can be used by Flink
processes to store data that can be recovered if the process is restarted with
access to the same working directory (e.g. via persistent volumes or restarting
the process on the same node).
The working directory will be default created in the temporary directory of the
executing node. Moreover, the path will include the resource id of the Flink
process. This will ensure that by default (random resource id), a newly started
Flink process will see an empty working directory.
This is an optional feature that might not be usable for all Flink deployments.
