Jun Qin commented on FLINK-14054: --------------------------------- [~aljoscha] I believe this has been implemented. Could you update the fix versions and close the JIRA? > Enable checkpointing via job configuration > ------------------------------------------ > > Key: FLINK-14054 > URL: https://issues.apache.org/jira/browse/FLINK-14054 > Project: Flink > Issue Type: Improvement > Components: Runtime / Checkpointing, Runtime / Configuration > Reporter: Jun Qin > Priority: Major > > Currently enabling checkpointing can only be done via the job code, see the > following quote from this Flink > [checkpointing|https://ci.apache.org/projects/flink/flink-docs-release-1.9/dev/stream/state/checkpointing.html#enabling-and-configuring-checkpointing] > doc: > {quote}By default, checkpointing is disabled. To enable checkpointing, call > {{enableCheckpointing(n)}} on the {{StreamExecutionEnvironment}}, where _n_ > is the checkpoint interval in milliseconds. > {quote} > This makes enabling checkingpointing after the job code has been released > difficult: one has to change and rebuild the job code. > In addition, not only for developer, making checkpointing enabling > configurable is also of interest for operation teams: > * They may want to enable checkpointing for production but disable in test > (e.g., to save storage space) > * They may want to try out with and without checkpointing to evaluate the > impact to the job behaviour and performance. > Therefore, this request.
