Summary: The patch makes sure that two parallel test threads will operate on different db paths. This enables using open source tools such as gtest-parallel to run the tests of a file in parallel. Example: ``` ~/gtest-parallel/gtest-parallel ./table_test``` Pull Request resolved: https://github.com/facebook/rocksdb/pull/4135 Differential Revision: D8846653 Pulled By: maysamyabandeh fbshipit-source-id: 799bad1abb260e3d346bcb680d2ae207a852ba84
