------------------------------------
Summary: Geography-aware, daisy-chaining replication (was: Geography-aware
replication)
> Geography-aware, daisy-chaining replication
> -------------------------------------------

> Key: CASSANDRA-8060
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8060
> Project: Cassandra
> Issue Type: Wish
> Reporter: Donald Smith
>
> We have three data centers in the US (CA in California, TX in Texas, and NJ
> in NJ), two in Europe (UK and DE), and two in Asia (JP and CH1). We do all
> our writing to CA. That represents a bottleneck, since the coordinator nodes
> in CA are responsible for all the replication to every data center.
> Far better if we had the option of setting things up so that CA replicated to
> TX , which replicated to NJ. NJ is closer to UK, so NJ should be responsible
> for replicating to UK, which should replicate to DE. Etc, etc.
> This could be controlled by the topology file.
> It would have major ramifications for latency architecture but might be
> appropriate for some scenarios.
