Dongjoon Hyun updated SPARK-28870:
----------------------------------
Affects Version/s: (was: 3.0.0)
3.1.0
> Snapshot event log files to support incremental reading
> -------------------------------------------------------
>
> Key: SPARK-28870
> URL: https://issues.apache.org/jira/browse/SPARK-28870
> Project: Spark
> Issue Type: New Feature
> Components: Spark Core
> Affects Versions: 3.1.0
> Reporter: Jungtaek Lim
> Priority: Major
>
> This issue tracks the effort on snapshotting the current status of
> KVStore/AppStatusListener and enable incremental reading to speed up
> replaying event logs.
> This issue will be on top of SPARK-29111 and SPARK-29261, as SPARK-29111 will
> add the ability to snapshot/restore from/to KVStore and SPARK-29261 will add
> the ability to snapshot/restore of state of (SQL)AppStatusListeners.
> Note that both SPARK-29261 and SPARK-29111 will not be guaranteeing any
> compatibility, and this issue should deal with the situation: snapshot
> version is not compatible with SHS.
