Stefania commented on CASSANDRA-10421:
--------------------------------------
Thank for explaining. So we'll have to use multiple identical txn log files,
one per data drive involved in the transaction.
Transaction is committed as long as at least one txn log file has the commit
flag, likewise for aborted. Some txn files may be missing the final flag but
they should not disagree on the final flag.
> Potential issue with LogTransaction as it only checks in a single directory
> for files

> When creating a new LogTransaction we try to create the new logfile in the
> same directory as the one we are writing to, but as we use
> {{[directories.getDirectoryForNewSSTables()|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/db/lifecycle/LogTransaction.java#L125]}}
> this might end up in "any" of the configured data directories. If it does,
> we will not be able to clean up leftovers as we check for files in the same
> directory as the logfile was created:
