Subject Cassandra JBOD disk configuration
Date Thu, 04 Sep 2014 11:48:49 GMT
Hi,

Let's imagine that I have one keyspace with one big table configured with
size tiered compaction strategy and nothing else. The disk configuration
would to have 10x 500GB disks, each mounted to separate directory.

Each directory would then be configured as a separate entry in
cassandra.yaml.

Over time data accumulates and I have at some point 4x 300GB sstables that
the cassandra would like to compact to one 1,2 TB sstable.

Since each directory has max 500GB disk space, that would not work. Right?

Is JBOD with more than 2 disks really usable with STCS? Probably LCS would
the only way to go in this case?

Cheers,
Hannu
