---------------------------------
Summary: Introduce Incremental savepoint
Key: FLINK-8753
URL: https://issues.apache.org/jira/browse/FLINK-8753
Project: Flink
Issue Type: New Feature
Components: State Backends, Checkpointing
Affects Versions: 1.5.0
Reporter: Sihua Zhou
Assignee: Sihua Zhou
Right now, savepoint goes through the full checkpoint path, take a savepoint
could be slowly. In our production, for some long term job it often costs more
than 10min to complete a savepoint which is unacceptable for a real time job,
so we have to turn back to use the externalized checkpoint instead currently.
But the externalized checkpoint has a time interval (checkpoint interval)
between the last time. So I proposal to introduce the increment savepoint which
goes through the increment checkpoint path.
