Stefania commented on CASSANDRA-10421:
--------------------------------------

I would prefer to keep a single transaction with a single log and have the 
transaction support multiple folders. 

As for listing, we pass all possible folders to the file lister; the sstable 
lister already scans all possible sstable folders. Listing one folder is 
already non atomic on Windows, so is listing on multiple folders on all 
platforms, but our add-on logic should still preserve the illusion of 
atomicity? 

> 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:
