Hi,all I have a cluster of 5 nodes, each node has a 4 cores cpu and 8 G Memory.
I use the 0.6-beta3 cassandra for testting. First , i insert 6,000,000 rows each of which is 1k bytes, the speed of write is so excited. But then ,when i read them each row at a time from two clients at the same time ,one of the client is very slow and use so long a time, i find that on each node the process of Cassandra occupy 7 G memory or so (use the "top" command), that puzzled me. Why read operation use so much of memory? May be i missed something? Thx. 2010-04-18 Bingbing Liu
