Aljoscha Krettek commented on FLINK-14054:
------------------------------------------
I thought for quite a while about something like this as well. There are some
relevant Jira issues and FLIPS alread:
-
https://cwiki.apache.org/confluence/display/FLINK/FLIP-59%3A+Enable+execution+configuration+from+Configuration+object
- FLINK-13566: Support checkpoint configuration through flink-conf.yaml
- FLINK-4947: Make all configuration possible via flink-conf.yaml and CLI.
> 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. Thanks.
