Hi All,

Can someone tell me about the conflict resolution = mechanisms provided by Cassandra?

= More specifically does Cassandra provides a way to define application speci= fic conflict resolution mechanisms (per row basis  / column basis)?&nb= sp;
           or 
Does it automatically manage the conflicts based on some s= ynchronization algorithms ?


Thank you
Emalayan
