Cassandra doesn't load any keyspaces by default. You have to manually do it
once. Using loadSchemaFromYAML method exposed by JMX

Have you tried starting it up with an empty system data dir ? Does it
pickup the schema from the yaml?

Hey,
As I understand it writes go directly to the commit log. Once a threshold
has been reached the data is shipped to a memtable, and again to an sstable.
1. How many memtables are created when a flush happens from a commit log?
One per CF?
2. Is there any space associated with an empty
of rows cached. Does this
effect write performance to other keyspaces in the cluster?

#2 was not meant to be trick question, it just came out like that :). what
i was after is the overhead associated with large number of keyspaces and
column families (i didn't mean empty memtables
