Update with more info: I'm still running into problems. Now I don't write more than 100 columns at a time, and I'm having lots of Stop-the-world gc pauses.
I'm writing into three column families, with memtable_operations = 0.3 and memtable_throughput = 64. There is now swapping, and full GCs are taking around 5 seconds. I'm running cassandra with a heap of 8 GB. Should I tune this somehow? Is any of this wrong? > > > > -----Original Message----- > > > From: Héctor Izquierdo Seliva [mailto:izquie...@strands.com] > > > Sent: April-05-11 8:30 > > > To: user@cassandra.apache.org > > > Subject: batch_mutate failed: out of sequence response > > > > > > Hi everyone.
