Storage Classes

[Boris Spasojevic]

Hi,

Which classes in Cassandra are used to store data?
Where can I find info on how Cassandra persists data?
Is there a way to periodically take a snapshot of the persisted data
without using the thrift client API? Does Cassandra persist data in a
file on in memory?

thanks in advance,
BoriS

State Objects

[Boris Spasojevic]

Hi all,

I am attempting to capture the states that Cassandra passes through for
some analyses. I have found the HeartBeatState, ApplicationState and
EndPointState (http://wiki.apache.org/cassandra/ArchitectureGossip)
classes but I cannot find a list of values which can appear in the
fields of the AplicationState (int version_; String state_;) mostly
state_, because version is, as I understood it, just for control. Could
anyone give any detail on how the states are organized, and what values
should I expect. 

Thanks in advance,
BoriS
