What happens while starting cassandra?

Question

  I am new to cassandra.. But i have some basic doubt on starting cassandra node.

When I have many keyspaces,does Cassandra load all the keyspaces into cache on startup?
or loads specific property of Keyspces to the cache?.

thanks in advance....

If you have cache saving enabled, Cassandra will load the most recent snapshot of the key and/or row caches. Otherwise, no specific preheating will be done. (Typically, Cassandra datasets are much larger than system memory.)
