C. Scott Andreas updated CASSANDRA-11610:
-----------------------------------------
Component/s: Distributed Metadata
> Revisit consistent range movement restrictions
> ----------------------------------------------
>
> Key: CASSANDRA-11610
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11610
> Project: Cassandra
> Issue Type: Improvement
> Components: Distributed Metadata
> Reporter: Brandon Williams
> Priority: Major
>
> I have a suspicion that we chose the wrong default by always having this on,
> with a flag to disable. We ran for a very long time without it, and at most
> a handful of people cared, with very few complaints. Now that we have this
> on, the majority who didn't care before but want to double even fairly small
> clusters now have to add a flag to disable it, and then are curious why they
> need to.
> Regardless of that, I think we need to at least make the restriction more
> lax; we currently block the simultaneous addition of nodes across the entire
> cluster, even they use NTS and have many DCs with different RF settings. We
> should at least allow simultaneous addition in multiple DCs.
