Sergey Shelukhin commented on HBASE-7516:
-----------------------------------------
This code will also have to change depending on compation algo, in particular
for level.
{code}
// exclude all files older than the newest file we're currently
// compacting. this allows us to preserve contiguity (HBASE-2856)
StoreFile last = filesCompacting.get(filesCompacting.size() - 1);
int idx = candidates.indexOf(last);
Preconditions.checkArgument(idx != -1);
candidates.subList(0, idx + 1).clear();
}{code}
I will try to get a prototype patch for store files into the refactor jira by
tomorrow, tomorrow we can discuss the necessary changes
> Make compaction policy pluggable

> the compaction algorithm pluggable too so that we can implement and play with
> other compaction algorithms.
