Subject Re: Monitoring compaction
Date Tue, 01 Jun 2010 16:50:28 GMT

to 0 during an import.  Is this advisable during any bulk import (say using
batch mutations or just lots and lots of thrift inserts)?

Also, when I asked "are folks open to..." I meant that I'm happy to code a
patch if anyone's interested.
