Jonathan Hsieh commented on HBASE-13012:
----------------------------------------
If we were to add mob flavored admin commands they would be:
{code}
// just merge files
void compactMob(TableName, byte[]famName) throws IOE
// full rewrite of all mobs to eliminate delmob files.
void majorCompactMob(TableName, byte[]famName) throws IOE
{code}
We're getting to the point where we might want to just add one more generic
compaction api, and have it use an enum argument so we don't have add others in
the future. Maybe we could have a CompactionType enum with MINOR, MAJOR, MOB
(merge some mobs, merge delmobs) and MOB_MAJOR (merge all mobs and eliminate
delmob files). It could look like this (and default to normal minor
compaction):
{code}
void compact(Tablename tn, byte[] famName, CompactionType ct);
{code}
Thoughts? I'm interested in other folks' opinions -- [~ramkrishna],
