Subject memtable sstable questions (0.6.4)
Date Wed, 20 Oct 2010 18:47:37 GMT
Hey,

As I understand it writes go directly to the commit log.  Once a threshold
has been reached the data is shipped to a memtable, and again to an sstable.

1. How many memtables are created when a flush happens from a commit log?
One per CF?

2. Is there any space associated with an empty memtable?

3. When a flush happens from a memtable to an sstable, does this create a
single new sstable?

4. Should compaction be turned off during a large data load?

Thanks.
