问题
I just noticed that my newly created sstable folder has a combination of numbers and letters attached. For my table "tweets" it looks like:
/var/lib/cassandra/data/twitter/tweets-a6da23906d8211e8a057ffb9a095df5c
on the disk. Does anybody know what this attached hash is?
Thanks! Christian

The folder name consists of table name, and table ID that is generated anew every time when the table is created - this is done to prevent race condition when table created, dropped, created, etc.
