> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Affects Versions: 0.8.0
> Reporter: Sylvain Lebresne

> Priority: Minor

>
> Right now, we choose the first replica for a counter increments based solely
> on what the snitch returns. If the clients requests are well balanced over
> the cluster and the snitch not ill configured, this should not be a problem,
> but this is probably too strong an assumption to make.
> The goal of this ticket is to change this to choose a random replica in the
> current data center instead.
