Hi,
Are there major overheads to running major compaction frequently? As much as I
know, it produces one Hfile for a region and processes delete markers and
version related drops. So, if this process has happened once say. a few mins
back then another major compaction should ideally not cause much harm.
Why I am trying to understand this is because Hbase also sets it to 24 hour
default (for time based compaction) and I am looking to lower it to say 20 mins
to reduce stress by spreading the load.
Or am I completely off-track?
Thanks,Sumit
