> Allow operators to disable 'ALTER ... DROP COMPACT STORAGE' statements

> Key: CASSANDRA-16733
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16733
> Project: Cassandra
> Issue Type: Bug
> Components: Legacy/CQL
> Reporter: Benjamin Lerer
> Assignee: Benjamin Lerer
> Priority: Normal
> Fix For: 4.0-rc2, 3.0.x, 3.11.x, 4.0-rc
>
>
> {{ALTER ... DROP COMPACT STORAGE}} statements have not been extensively
> tested and suffer from several issues like:
> * As COMPACT tables did not have primary key liveness there empty rows
> inserted AFTER the ALTER will be returned whereas the one inserted before
> the ALTER will not.
> * Also due to the lack of primary key liveness the amount of SSTables being
> read will increase resulting in slower queries (CASSANDRA-16675)
> * After DROP COMPACT it becomes possible to ALTER the table in a way that
> makes all the row disappears
> * There is a loss of functionality around null clustering when dropping
> compact storage (CASSANDRA-16069)
> To avoid running into those issues this ticket will introduce a new flag that
> allow operators to disable those statements on their clusters.
