Hi All,
I posted a similar message on the google groups page. Hopefully, I'll get more
feedback here.
I just started reading about dynamo and Cassandra and I am thinking
about possibly using cassandra for my system.
I was reading the dynamo paper and they mentioned about a preference
list for a particular key. Is this preference list configurable?
How does Cassandra choose which nodes are in the preference list?
Also, are the number of replica for each key/column configurable? For
example, can I set the replication factor per key/value?
I read that Cassandra has optimistic replication. What exactly does
that mean? Underneath the hood, how does cassandra maintain/detect the
number of replicas? Does it aggressively replicates an item, when it
detects that the number of replica of a particular item goes below the
specified repliation factor?
Is the replication strategy (when to replicate, aggresiveness, etc)
configurable too?
Thanks,
Harold
