Alternatively, you can directly create `DBWithThreadMode<MultiThreaded>` without enabling the crate feature. -## Portable builds - -RocksDB's build, unlike Cargo, will default to setting `-march=native`, which -generate code that fully takes advantage of build machine's CPU's features. -This may create a binary that isn't compatible with other CPUs on the same -architecture.
