I am new to Cassandra and was curious about the following scenario... Lets say i have a ring of 5 servers. Ultimately I would like each server to be a full replication of the next (master-master-*).
In a presentation i watched today on Cassandra, the presenter mentioned that the ring members will shard data and route your requests to the right host when they come in to a server that doesnt physically contain the value you wanted. To the client requesting this is seamless excwpt for the added latency. If i wanted to avoid the routing and latency and ensure every server had the full data set, do i have to write with a consistency level of ALL and wait for all of those writes to return in my code, or can i write with a CL of 1 or 2 and let the ring propagate the rest of the copies to the other servers in the background after my code has continued executing? I dont mind eventual consistency in my case, but i do (eventually) want all nodes to have all values and cannot tell if this is default behavior, or if sharding is the default and i can only force duplicates onto the other servers explicitly with a CL of ALL. Best, Riyad
