// IncreaseParallelism sets the parallelism.

// By default, RocksDB uses only one background thread for flush and
// compaction. Calling this function will set it up such that total of
// `total_threads` is used. Good value for `total_threads` is the number of
// cores. You almost definitely want to call this function if your system is
// bottlenecked by RocksDB.
