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. -- This message was sent by Atlassian Jira (v8.3.2#803003)
