             Summary: Allow configuring checkpoints in Flink Runner 
PipelineOptions
                 Key: BEAM-1812
                 URL: https://issues.apache.org/jira/browse/BEAM-1812
             Project: Beam
          Issue Type: Improvement
          Components: runner-flink
            Reporter: Aljoscha Krettek
            Assignee: Aljoscha Krettek


Flink allows fine grained configuration of checkpointing: 
https://github.com/aljoscha/flink/blob/master/flink-streaming-java/src/main/java/org/apache/flink/streaming/api/environment/CheckpointConfig.java

Among other things this allows to configure externalised checkpoints, which is 
a valuable feature when running a job in production because it allows restoring 
a job after a failure as from a savepoint.
