Date Thu, 07 May 2009 02:55:30 GMT

Edward J. Yoon commented on HAMA-182:
-------------------------------------

A lot of families have to flush often. If I reduces the number of families, it's ok. However,
I'm not sure whether small families are worth anything.

> The all columns are stored in a single column family. I propose to separate column families
by column index range so that we reduces I/O during column-based process.
