> Key: FLINK-22659
> URL: https://issues.apache.org/jira/browse/FLINK-22659
> Project: Flink
> Issue Type: Bug
> Components: Documentation
> Affects Versions: 1.13.0
> Reporter: wangqinghuan
> Assignee: Rainie Li
> Priority: Minor
>
> Flink deployment configuration describe how to configure checkpointing in
> flink-conf.yaml[https://ci.apache.org/projects/flink/flink-docs-master/docs/deployment/config/]
> {quote}*Checkpointing*
> You can configure checkpointing directly in code within your Flink job or
> application. Putting these values here in the configuration defines them as
> defaults in case the application does not configure anything.
> {quote}
> *
>
> {quote}{{state.backend}}: The state backend to use. This defines the data
> structure mechanism for taking snapshots. Common values are {{filesystem}} or
> {{rocksdb}}.
> {quote} *
> {quote}{{state.checkpoints.dir}}: The directory to write checkpoints to. This
> takes a path URI like _s3://mybucket/flink-app/checkpoints_ or
> _hdfs://namenode:port/flink/checkpoints_.
> {quote}
> *
> {quote}{{state.savepoints.dir}}: The default directory for savepoints. Takes
> a path URI, similar to {{state.checkpoints.dir}}.
> {quote}
> In my test for Flink-1.13.0, however,Flink checkpointing was not enabled
> without 'execution.checkpointing.interval' value in flink-conf.yaml. In order
> to enable checkpointing in case the application does not configure anything,
> we need to configure these values in flink-conf.yaml.
> * {{state.backend}}:
> * {{state.checkpoints.dir:}}
> * {{state.savepoints.dir:}}
> * execution.checkpointing.interval:
> {{'execution.checkpointing.interval' value missing in document.}}
