I noticed that the LOG files in each RocksDB kv store grow indefinitely. I could set them up via logrotate but it would be cumbersome and against the grain. Tried to figure out if RocksDB has a configuration file and I don't have a definite answer yet (the one mention is for version 4.3).
RocksDB does expose methods for this very purpose: setMaxLogFileSize setMaxManifestFileSize setKeepLogFileNum Samza should use these to provide a sensible default out-of-the-box.
