What is your gc_grace set to? Are your findings before or after this time after the deletion?

Hi all, When I delete some rowkeys programmatically I can see two rowkeys remains in the column family. I think it is due to tombstones. Is there a way to remove it when deleting rowkeys. Can I run compaction programmatically after deletion? will it remove all these remaining rowkeys. Thanks, Kasun.
