[jira] [Created] (FLINK-14054) Enable checkpointing via job
configuration
Jun Qin created FLINK-14054:
-------------------------------
Summary: Enable checkpointing via job configuration
Key: FLINK-14054
URL: https://issues.apache.org/jira/browse/FLINK-14054
Project: Flink
Issue Type: Improvement
Components: Runtime / Configuration
Reporter: Jun Qin
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.
