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.
