Sam Tunnicliffe commented on CASSANDRA-14092:
---------------------------------------------
{quote}Since 4.0 was not released, and it will come out with this fix it's
impossible that someone will hit this on 4.0, but I don't see any problem in
keeping the scrub option for the lazy ones upgrading from 3.x without fixing
their SSTables beforehand.
{quote}
yeah, this was the scenario I was thinking about.
{quote}I now wonder if this notice has gotten to big and is cluttering the
NEWS.txt file too much - what may confuse users looking for upgrade
instructions - and we should maybe create a new WARNING/IMPORTANT file and add
a pointer to it in the NEWS.txt file instead?
{quote}
I tend to agree with you. Even if adding another file is less than ideal, it's
probably better than adding a large, unchanging header as that's likely just
going to lead to more users not properly reading it and missing critical info
about other future upgrades. So I'd be +1 on adding a new file
({{CASSANDRA\-14092.txt}} maybe?) and just a brief explanation of the severity
of the issue plus a *very* clear pointer to more detailed file at the top of
{{NEWS.txt}}. I think you should keep the
{code:java}
WARNING: MAXIMUM TTL EXPIRATION DATE NOTICE
--------------------------------------------
(General upgrading instructions are available in the next section)
The maximum expiration timestamp that can be represented by the storage engine
is 2038-01-19T03:14:06+00:00,
which means that inserts with TTL that expire after this date are not currently
supported.
{code}
and add the pointer after that.
1 nit on the text in {{NEWS.txt}}, you have a double "the" in the sentence
{{"As time progresses, the maximum supported TTL will be gradually reduced as
the the maximum expiration date approaches."}}
Extracting the news text to a new file notwithstanding, I'm +1 on the latest
patches. Thanks for all the hard work on this [~pauloricardomg]

> URL: https://issues.apache.org/jira/browse/CASSANDRA-14092
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Reporter: Paulo Motta
> Assignee: Paulo Motta
> Priority: Blocker
> Fix For: 2.1.20, 2.2.12, 3.0.16, 3.11.2
>
>
> 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.
