> Implement WAL logs compaction and compression after checkpoint
> --------------------------------------------------------------
>
> Key: IGNITE-5938
> URL: https://issues.apache.org/jira/browse/IGNITE-5938
> Project: Ignite
> Issue Type: Improvement
> Components: persistence
> Affects Versions: 2.1
> Reporter: Alexey Goncharuk
> Assignee: Ivan Rakov
> Fix For: 2.4
>
>
> Currently, we simply move WAL segments to archive when WAL segment is written
> and delete when checkpoint history becomes too old.
> Archived WAL segment contains physical delta records that are no longer
> needed for rebalancing, so these records may be thrown away. In order to
> optimize disk space and delta WAL rebalancing, we can do the following:
> 1) Clean the WAL segments from the physical records
> 2) Compress the cleaned segments (I expect this to be very effective since we
> write full objects)
