> For inotify, we want to be able to read transactions from in-progress edit
> log segments so we can serve transactions to listeners soon after they are
> committed. This JIRA works toward ensuring that we do not send unsync'ed
> transactions back to the client by 1) discarding in-progress segments if we
> have a finalized segment starting at the same transaction ID and 2) if there
> are no finalized segments at the same transaction ID, using only the
> in-progress segments with the largest seen lastWriterEpoch. See the design
> document for more background and details.
