> This is a feature request to expose RocksDB's maxOpenFiles setting as a Samza
> Parameter. It's needed to prevent large databases from opening more files
> than what's allowed by ulimit settings and causing the container to fail.

> // Number of open files that can be used by the DB. You may need to
> // increase this if your database has a large working set. Value -1 means
> // files opened are always kept open. You can estimate number of files based
> // on target_file_size_base and target_file_size_multiplier for level-based
> // compaction. For universal-style compaction, you can usually set it to -1.
