Jason Brown reassigned CASSANDRA-8060: -------------------------------------- Assignee: (was: Jason Brown) > Geography-aware, distributed replication > ---------------------------------------- > > Key: CASSANDRA-8060 > URL: https://issues.apache.org/jira/browse/CASSANDRA-8060 > Project: Cassandra > Issue Type: Wish > Reporter: Donald Smith > Priority: Major > > 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. > The replication could be organized in a tree-like structure instead of a > daisy-chain. > It would require architectural changes and would have major ramifications for > latency but might be appropriate for some scenarios. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
