JVM GC pause? If so the improved JVM options in 0.6.2 should help some. Increasing heap size is also a good candidate to help. On Thu, May 27, 2010 at 2:01 PM, Jones, Nick wrote: > Hi everyone, > I'm using the Cassandra gem and have been trying to optimize inserting > 400k-1M columns per row.

Large column/row inserts

2010-05-27 Thread Jones, Nick
Hi everyone, I'm using the Cassandra gem and have been trying to optimize inserting 400k-1M columns per row. I'm currently batching 1k column inserts and see about 130ms response times; however, every 19th insert takes 3.3s. Can anyone think of a reason for this? Thanks. Nick Jones
