Subject [jira] [Commented] (CASSANDRA-14092) Max ttl of 20 years will overflow localDeletionTime
Date Sun, 03 Dec 2017 22:05:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-14092?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16276120#comment-16276120
] 

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.

> 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.
