ASF GitHub Bot commented on FLINK-4340: --------------------------------------- Github user wenlong88 commented on the issue: https://github.com/apache/flink/pull/2345 3q, @aljoscha Maybe we can use different db instance for different key group. this approach can only work well when key group number is limited to a certain number which can not be too large. Since the max number of key groups is limited by the max parallelism config, I think different db instances can work. > Remove RocksDB Semi-Async Checkpoint Mode > ----------------------------------------- > > Key: FLINK-4340 > URL: https://issues.apache.org/jira/browse/FLINK-4340 > Project: Flink > Issue Type: Improvement > Components: State Backends, Checkpointing > Affects Versions: 1.1.0 > Reporter: Aljoscha Krettek > Assignee: Aljoscha Krettek > > This seems to be causing to many problems and is also incompatible with the > upcoming key-group/sharding changes that will allow rescaling of keyed state. > Once this is done we can also close FLINK-4228. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
