The conversation continues in ticket [CASSANDRA-16226](https://issues.apache.org/jira/browse/CASSANDRA-16226) with the aim of ensuring there are no huge performance regressions for common queries when you upgrade from 2.x to 3.0 with Compact Storage tables or drop it from a table on 3.0+. + +#### **Added** +In 4.0 there is a plan to drop compact storage and related code, but the community noticed behavioral changes such as differences in visible behavior between "normal" and compact tables. Solutions are being discussed as part of [CASSANDRA-16217](https://issues.apache.org/jira/browse/CASSANDRA-16217). Review comment: Ah yes, thank you!
