Vincent White updated CASSANDRA-14948:
--------------------------------------
Fix Version/s: 3.11.x
Status: Patch Available (was: Open)
> Backport dropped column checks to 3.11
> --------------------------------------
>
> Key: CASSANDRA-14948
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14948
> Project: Cassandra
> Issue Type: Bug
> Reporter: Vincent White
> Assignee: Vincent White
> Priority: Minor
> Fix For: 3.11.x
>
>
> This is a follow on from CASSANDRA-14913 and CASSANDRA-14843 that introduced
> some fixes to prevent and mitigate data corruption caused by dropping a
> column then re-adding it with the same name but an incompatible type (e.g.
> simple int to a complex map<>) or different kind (regular/static).
> This patch backports the checks that now exist in trunk. This does include
> adding a column to the dropped_columns table to keep track of static columns
> like trunk, not sure it we are able to make that change in 3.11.x.
> Also not sure what our stance on backporting just the isValueCompatibleWith
> check to 3.0 is. I'd be for it since it prevents recreating a simple column
> as a map (or vice-versa) which will basically always lead to corruption.
> ||C* 3.11.x||
