Subject Understand eventually consistent
Date Fri, 18 Feb 2011 01:11:48 GMT

Why is Cassandra called eventually consistent data store? Wouldn't it be
consistent if QUORAM is used?

Another question is when I specify replication factor of 3 and write with
factor of 2 and read with factor of 2 then what happens?

1. When write occurs cassandra will return to the client only when the
writes go to commit log on 2 nodes successfully?

2. When read happens cassandra will return only when it is able to read from
2 nodes and determine that it has consistent copy?
