Subject Memtable live ratio of infinity
Date Thu, 15 Dec 2011 22:25:17 GMT
Hi All,

I saw the following log message today on a node running cassandra 1.0.5:

"WARN [pool-1-thread-1] 2011-12-15 20:28:53,915 Memtable.java (line 174) setting live ratio
to maximum of 64 instead of Infinity"

I guess this means calculated throughput is either very low or the Memtable is huge.  Either
way, the following line in Memtable looks a bit weird:

double newRatio = (double) deepSize / currentThroughput.get();

Has anyone seen this warning before?
