Paulo Motta commented on CASSANDRA-14092:
-----------------------------------------
I think that CASSANDRA-8099 already removed this limitation from the storage
engine by encoding {{localDeletionTime}} as a varint, so it should be
relatively easy to update the code to represent {{localDeletionTime}} as a long
instead.
> Max ttl of 20 years will overflow localDeletionTime

> Key: CASSANDRA-14092
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14092
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Reporter: Paulo Motta
>
> CASSANDRA-4771 added a max value of 20 years for ttl to protect against [year
> 2038 overflow bug|https://en.wikipedia.org/wiki/Year_2038_problem] for
> {{localDeletionTime}}.
> It turns out that next year the {{localDeletionTime}} will start overflowing
> with the maximum ttl of 20 years ({{System.currentTimeMillis() + ttl(20
> years) > Integer.MAX_VALUE}}), so we should remove this limitation.
