---------------------------------------
Summary: Remove COMPACT STORAGE internals before 4.0 release
Key: CASSANDRA-13994
URL: https://issues.apache.org/jira/browse/CASSANDRA-13994
Project: Cassandra
Issue Type: Improvement
Reporter: Alex Petrov
Assignee: Alex Petrov
Priority: Blocker
Fix For: 4.0
4.0 comes without thrift (after [CASSANDRA-11115]) and COMPACT STORAGE (after
[CASSANDRA-10857]), and since Compact Storage flags are now disabled, all of
the related functionality is useless.
There are still some things to consider:
1. One of the system tables (built indexes) was compact. For now, we just added
{{value}} column to it to make sure it's backwards-compatible, but we might
want to make sure it's just a "normal" table and doesn't have redundant columns.
2. Compact Tables were building indexes in {{KEYS}} mode. Removing it is
trivial, but this would mean that all built indexes will be defunct. We could
log a warning for now and ask users to migrate off those for now and completely
remove it from future releases. It's just a couple of classes though.
