Define a conflict. What kind  of conflict you are talking about?

There're no transactions. For simple inserts/updates latest column timestamp wins. Timestamp
is provided by application.

Counter columns has some conflict resolution, but overall counter columns not working perfect.

Subject: [Cassandra] Conflict resolution in Cassandra

Hi All,

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

More specifically does Cassandra provides a way to define application specific conflict resolution
mechanisms (per row basis  / column basis)?
Does it automatically manage the conflicts based on some synchronization algorithms ?

Thank you

Best regards / Pagarbiai
