Summary: … to CFOptions https://github.com/facebook/rocksdb/pull/6615 made several compression related options dynamically changeable. They are moved to MutableCFOptions. However, they are not copied back to ColumnFamilyOptions, so the changed values are not written to option files and for some other uses. Fix it by copying them back. Pull Request resolved: https://github.com/facebook/rocksdb/pull/6668 Test Plan: Add a unit test to make sure that when a MutableCFOptions is converted to CFOptions and back to MutableCFOptions, they stay the same. This test would fail without the fix. Reviewed By: ajkr Differential Revision: D20923999 fbshipit-source-id: c3bccd6923b00d677764e2269bed6a95ad7ed780
