-------------------------------------
Summary: Parallelize execution of (async) snapshots in
AsyncCheckpointRunnable
Key: FLINK-6049
URL: https://issues.apache.org/jira/browse/FLINK-6049
Project: Flink
Issue Type: Improvement
Components: State Backends, Checkpointing
Affects Versions: 1.3.0
Reporter: Stefan Richter
Fix For: 1.3.0
After the changes from [FLINK-6048], it would make sense to parallelize the
execution of the `RunnableFuture`s of (async) snapshot in
`AsyncCheckpointRunnable`. Currently, `AsyncCheckpointRunnable` is a thread
that runs parallel, but executes each snapshot sequentially. The reason is,
that previously only keyed state backends had support for async snapshots.
