The default Cassandra systems keyspace system is present in all Cassandra installations.

Judging from the output of the describe keyspace command the keyspace it is used partly for "persistent metadata for the local node" (LocationInfo) and partly for "hinted handoff data".

What persistent metadata for the local node is stored in system/LocationInfo?
What is the definition of hinted handoff in Cassandra terminology?
What hinted handoff data is stored in the system keyspace?
