Description
After an incremental repair we iterate over all sstables and split them in two parts, one containing the repaired data and one the unrepaired. We could in theory double the number of sstables on a node.
To avoid this we could make anticompaction also do a compaction, for example, if we are to anticompact 10 sstables, we could anticompact those to 2.
Note that we need to avoid creating too big sstables though, if we anticompact all sstables on a node it would essentially be a major compaction.
