Uint POC seems to be OK as well on the latency side. There are latencies on 2 completely different tests with even 2 diff test tooling:
10 averaged runs latency
[^screenshot-3.png]

Averaged latency on a 1h test

> 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.
