Nikhil Benesch 17339dc2f3 Add table property tracking number of range deletions (#4016) ... Summary: Add a new table property, rocksdb.num.range-deletions, which tracks the number of range deletions in a block-based table. Range deletions are no longer counted in rocksdb.num.entries; as discovered in PR #3778, there are various code paths that implicitly assume that rocksdb.num.entries counts only true keys, not range deletions. /cc ajkr nvanbenschoten Closes https://github.com/facebook/rocksdb/pull/4016 Differential Revision: D8527575 Pulled By: ajkr fbshipit-source-id: 92e7edbe78fda53756a558013c9fb496e7764fd7		2018-06-26 20:27:35 -07:00
