------------------------------------
Summary: 'execution.checkpointing.interval' missing in Flink doc
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
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.}}}}
