Sergey Shelukhin commented on HBASE-5626:
-----------------------------------------
IMHO it may make sense to have it in java... if we could have some sort of
pluggability in policy and compactor, which would cause them to not read or
write the files but just report what they "read" and "wrote", we could use
normal compaction code without having to keep the script in sync.

> A tool to run compaction simulations would be a nice to have. We could use
> it to see how well an algo ran under different circumstances loaded w/
> different value types with different rates of flushes and splits, etc.
> HBASE-2462 had one (see in patch). Or we could try doing it using something
