Hey guys,
I have a ec2 debian cluster consisting of several nodes running 0.7.5 on
ephimeral disks.
These are fresh installs and not upgrades.
The commitlog is set to the smaller of the disks which is around 10G in size
and the datadir is set to the bigger disk.
The config file is basically the same as the one supplied by the default
installation.
Our applications write to the cluster. After about a day of writing we
started noticing the commitlog disk filling up. Soon we went over the disk
limit and writes started failing. At this point we stopped the cluster.
Over the course of the day we inserted around 25G of data. Our columns
values are pretty small.
I understand that cassandra periodically cleans up the commitlog directories
by generating sstables in datadir. Is there any way to speed up this
movement from commitog to datadir?
Thanks!
