Summary: Several functions of UniversalCompactionPicker share most of the parameters. Move these functions to a class with those shared arguments as class members. Hopefully this will make code slightly easier to maintain. Pull Request resolved: https://github.com/facebook/rocksdb/pull/5639 Test Plan: Run all existing test.
