--------------------------------------------
Summary: Support limiting job history size
Key: FLINK-17998
URL: https://issues.apache.org/jira/browse/FLINK-17998
Project: Flink
Issue Type: Improvement
Components: Runtime / Configuration
Reporter: Daniel Laszlo Magyar
Flink history server stores information for an unlimited number of completed
jobs, which is inconvenient to dig through on long-running instances and might
cause performance degradation in the long run.
Spark for example addresses this issue by limiting the number of jobs to keep
by a [configuration
parameter|https://spark.apache.org/docs/2.2.0/monitoring.html#spark-configuration-options]
{{spark.history.retainedApplications}} with a default of 50 jobs to keep.
Introducing a similar configuration option to the Flink history server would
improve the usability and performability of long-running history server
instances.
