Summary: Add a new option ReadOptions.auto_prefix_mode. When set to true, iterator should return the same result as total order seek, but may choose to do prefix seek internally, based on iterator upper bounds. Also fix two previous bugs when handling prefix extrator changes: (1) reverse iterator should not rely on upper bound to determine prefix. Fix it with skipping prefix check. (2) block-based filter is not handled properly. Pull Request resolved: https://github.com/facebook/rocksdb/pull/6314 Test Plan: (1) add a unit test; (2) add the check to stress test and run see whether it can pass at least one run.
