-------------------------------------------
This seems to have broken the upgrade tests, [~ifesdjeen] can you take a look?

> Minimal 4.0 COMPACT STORAGE backport
> ------------------------------------
>
> Key: CASSANDRA-16217
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16217
> Project: Cassandra
> Issue Type: Bug
> Components: Legacy/CQL
> Reporter: Alex Petrov
> Assignee: Alex Petrov
> Priority: Normal
> Fix For: 4.0-beta4
>
>
> There are several behavioural changes related to compact storage, and these
> differences are larger than most of us have anticipated: we first thought
> there’ll be that “appearing column”, but there’s implicit nulls in
> clusterings thing, and row vs column deletion.
> Some of the recent issues on the subject are: CASSANDRA-16048, which allows
> to ignore these differences. The other one was trying to improve user
> experience of anyone still using compact storage: CASSANDRA-15811.
> Easily reproducible differernces are:
> (1) hidden columns show up, which breaks SELECT * queries
> (2) DELETE v and UPDATE v WITH TTL would result into row removals in
> non-dense compact tables (CASSANDRA-16069)
> (3) INSERT allows skipping clusterings, which are filled with nulls by
> default.
> Some of these are tricky to support, as 15811 has shown. Anyone on OSS side
> who might want to upgrade to 4.0 while still using compact storage might be
> affected by being forced into one of these behaviours.
> Possible solutions are to document these behaviours, or to bring back a
> minimal set of COMPACT STORAGE to keep supporting these.
> It looks like it is possible to leave some of the functionality related to
> DENSE flag and allow it to be present in 4.0, but only for these three (and
> potential related, however not direrclty visible) cases.
> [~e.dimitrova] since you were working on removal on compact storage, wanted
> to reassure that this is not a revert of your patch. On contrary: your patch
> was instrumental in identifying the right places.
