> 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.
