Each table has unique id (suffix). If you drop and then recreate table with the 
same name it gets new id.

Try
SELECT keyspace_name, table_name, id FROM system_schema.tables ;
to determinate actual ID.

You can limit request to specific keyspace or table.

Hello,


I am using Cassandra 3.0.9 and I have encountered an issue where the nodes in 
my 3 node cluster have vastly different amounts of data even though they should 
be roughly the same. When I looked through the data directory for my database 
on two of the nodes, I see a number of directories with the same prefix, eg:


periodicReading-76eb7510096811e68a7421c8b9466352,
periodicReading-453d55a0501d11e68623a9d2b6f96e86
...



Only one directory with a specific table name prefix has a current date and the 
rest are older.


In contrast, on the node with the least space used, each directory has a unique 
prefix (not shared).


I am wondering what the contents of a Cassandra database directory should look 
like. Are there supposed to be multiple entries for a given table or just one?


If just one, what would be a procedure to determine if the other directories 
with the same table are junk that can be removed.



Thanks,


Jason
