Aleksey Yeschenko commented on CASSANDRA-7835:
----------------------------------------------
Which RF would you even use? A batch can span multiple keyspaces. Would have to
have a global N set in the yaml. Not that it's an issue, but we really don't
like adding new configuration parameters where avoidable.
Also, while we do write only to 2 *other* nodes, you need 3 nodes to go down
for a batch to be lost (the coordinator itself, and the two other replicas).
This should be enough.
> Atomic batches with an option to specifcy RF-1 batch log entries

> Key: CASSANDRA-7835
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7835
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: Ryan Svihla
> Priority: Minor
>
> Some users seem to be concerned with there only being 2 batch log entries on
> a write and would like more guarantees on consistency, potentially even
> spanning data centers in exchange for less performance.
> Would like the option to have these span data centers.
