Work Description: KevinGG opened a new pull request #12283:
URL: https://github.com/apache/beam/pull/12283
1. Removed unnecessary path components from the cache file paths.
2. Obfuscated the variable name in the cache key that is used as part of
cache file path so that it only takes constant length in the file
path.
