Subject what is taking up my JVM heap space?
Date Fri, 05 Aug 2011 02:38:57 GMT
I ran my cassandra cluster on one node, inserted about 500000 rows,
each about 400 bytes, then the heap went up to 800MB, and constantly
goes into full GC. I guessed that the memtable was probably taking a
lot of space, so I did a node tool flush, so that
all memtable are changed to 0. after this, the heap came down a bit,  to 500MB.

but I thought it should be close to 0 right after the flush?? or else
what is taking up the space?
I'm still trying to look at the hprof file to figure out, but it seems
difficult too


Thanks
Yang
