Subject Re: Compaction after bulk-load

How many region servers do you have in the cluster ?

Would there be concurrent write load on the cluster if you choose to run major
compaction ? I ask this because the concurrent write would be slowed down
by the major compaction and compacting 10 TB of data would take some time.
