[GitHub] activemq-artemis pull request #2402: NO-JIRA: Clarify journal-buffer-timeout...

GitHub user cshannon opened a pull request:

    NO-JIRA: Clarify journal-buffer-timeout documentation

    Clarify how to disable the buffer timeout.  On one of my test brokers I disabled journal-sync-transactional and journal-sync-non-transactional as data loss is not a big deal.  In this scenario I just want to write directly to the file and not use a timed buffer and let the OS handle data syncing, however it was not clear on how to accomplish this.  Looking at the code I discovered setting the timeout to 0 will disable the buffer so I'm adding a comment in case others want to do the same.

    I know, either way, this is just to update the documentation to say that 0 will disable the timed buffer

    You need to disable data-sync too if you want to rely just on the sync provided by OS ie just application failure protection AFAIK.
    Without being too OT, provided you have enough RAM, the mapped journal is specifically built to address this use case :)
