Benedict Elliott Smith commented on CASSANDRA-14227:
----------------------------------------------------
This is the canonical example that was given in the original thread more than a
year ago, i.e. that a cluster should not write files that are incompatible with
the version we are upgrading from until the operator agrees the upgrade has
been successful, yes. If there are performance or other regressions encountered
during an upgrade, recovery should be as simple as restarting with the prior
version (until the operator decides the new version is performing adequately).
This minimises risks, without fully eliminating them.

> The maximum expiration timestamp that can be represented by the storage
> engine is
> 2038-01-19T03:14:06+00:00 due to the encoding of {{localExpirationTime}} as
> an int32.
> On CASSANDRA-14092 we added an overflow policy which rejects requests with
> expiration above the maximum date as a temporary measure, but we should
> remove this limitation by updating the storage engine to support at least the
> maximum allowed TTL of 20 years.
