Subject Re: Is all meta data aways in memory when hbase are running?
Date Thu, 17 Feb 2011 04:27:18 GMT

HBase clients caches _accessed_ region location information in heap. In 
addition, whenever it locates a new region, it will perform a region 
location prefetch for the adjacent regions, and the default number of 
prefetched region location info is configurable (10 by default).

It's what you wanted to ask, right?
