Hi,

I received a request from a client to delete duplicate records from a table which is very large in size. 

Delete queries (~2 Billion) are provided via file, and we have to execute that file in DB. Last time it lasted for two days. I feel there must be another way to delete records in an efficient manner

Maybe the delete "queries" are poorly written.  Maybe there's no supporting index.
