-----------------------------------------
Summary: 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
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||
