> CFS.setCompressionParameters() method can affect schema globally
> ----------------------------------------------------------------
>
> Key: CASSANDRA-12949
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12949
> Project: Cassandra
> Issue Type: Bug
> Components: Legacy/Distributed Metadata
> Reporter: Aleksey Yeschenko
> Assignee: Alex Petrov
> Priority: Normal
> Fix For: 2.2.x, 3.0.x, 3.11.x
>
>
> CFS.setCompressionParameters() method can affect schema globally, despite being intended as a way to change compression locally on just one node, for experimental purposes.
> CFS.setCompactionParamaters(), on the other hand, works correctly, by never modifying the {{CFMetaData}} object in-place.
> Its modification by CFS.setCompressionParameters() means that any subsequent ALTER that affects that table will pick up the change made by CFS.setCompressionParameters() and disseminate it to the rest of the cluster.
