-------------------------------------
Summary: Asyncronous snapshots for heap-based keyed state backends
Key: FLINK-5958
URL: https://issues.apache.org/jira/browse/FLINK-5958
Project: Flink
Issue Type: Improvement
Components: State Backends, Checkpointing
Affects Versions: 1.3.0
Reporter: Stefan Richter
Assignee: Stefan Richter
The synchronous checkpointing mechanism of all heap-based keyed state backends
is often painful for users because it stops processing for the duration of the
checkpoint.
We could implement an option for heap-based keyed state backends that allows
for asynchronous checkpoints, using copy-on-write.
