Jon Haddad updated CASSANDRA-19973:
-----------------------------------
Resolution: Won't Fix
Status: Resolved (was: Triage Needed)
> Allow TWCS to use UCS within a window
> -------------------------------------
>
> Key: CASSANDRA-19973
> URL: https://issues.apache.org/jira/browse/CASSANDRA-19973
> Project: Apache Cassandra
> Issue Type: Improvement
> Reporter: Jon Haddad
> Priority: Normal
>
> Since TWCS is using STCS within a window, it makes the sstables inelligible
> for zero copy streaming. That is a bummer, because time series use cases
> typically have denser nodes. This makes the penalty from using TWCS very
> impactful when adding new nodes.
> We should be able to use UCS for the window so we can get the benefits of ZCS
> when bootstrapping new nodes.
