Summary: Operations like Seek/Next/Prev sometimes take too long to complete when there are many internal keys to be skipped. Adding an option, max_skippable_internal_keys -- which could be used to set a threshold for the maximum number of keys that can be skipped, will help to address these cases where it is much better to fail a request (as incomplete) than to wait for a considerable time for the request to complete. This feature -- to fail an iterator seek request as incomplete, is disabled by default when max_skippable_internal_keys = 0. It is enabled only when max_skippable_internal_keys > 0. This feature is based on the discussion mentioned in the PR https://github.com/facebook/rocksdb/pull/1084. Closes https://github.com/facebook/rocksdb/pull/2000 Differential Revision: D4753223 Pulled By: sagar0 fbshipit-source-id: 1c973f7
