Marcus Eriksson commented on CASSANDRA-10422:
---------------------------------------------
[~aweisberg] (sorry for not replying quicker) - isIncremental is for telling
the other nodes which sstables to use when doing the repair (for merkle tree
calculation and streaming, if isIncremental is true, we will only use the
sstables that are not marked as repaired) - isGlobal is used to tell the other
nodes if we can actually do the anticompaction - if all nodes that have the
range are included in the repair.
> Avoid anticompaction when doing subrange repair

> If we do split the owned range in say 1000 parts, and then do one repair
> each, we could potentially anticompact every sstable 1000 times (ie, we
> anticompact the repaired range out 1000 times). We should avoid
> anticompacting at all in these cases.
