Chen Luo commented on ASTERIXDB-2324:
-------------------------------------

[~amoudi] Hi Abdullah, can you confirm is this indeed a bug? Or this behavior is allowed? (I personally think this is incorrect since after deleting a file all pages should be removed from the buffer cache...)

> The typical workflow for deleting an index is to first deactive and then destroy. During deactive, we close the index file from the buffer cache, which internally removes the file info (however, the pages are still in the buffer cache). We then call destroy to delete that file. However, most callers use the file reference as the parameter, which causes file pages are not cleaned because the file info does not exist any more.
