> Currently, Major compaction compacts a whole table in one step. If a table is
> partition and has a lot of data this operation can take a lot of time and it
> risks getting write conflicts at the commit stage. This can be improved to
> work partition by partition. Also, for each partition it will create one
> snapshot instead of 2 snapshots (truncate+IOW) created now when compacting
> the whole table in one step.
