We have a five node cluster, using replication factor of 3. The application is
only sending write requests at this point - we'd like to gain some operation
experience with it first before start read from it.
We are seeing over a hundred compaction activities on each server, some of them
are for HintsColumnFamily.
Each machine has 32 GB memory, two disk arrays, one with raid 0 for commit log,
one with raid 5 for data. We are using version 0.6.1, and pretty much the out
of the box storage.xml.
Is this normal? Where should we look for tuning?
Here is the ring info
