Class PathLock

Object
io.delta.storage.internal.PathLock
public class PathLock extends Object
A lock that provides per-file-path `acquire` and `release` semantics. Can be used to ensure that no two writers are creating the same external (e.g. S3) file at the same time.

Note: For all APIs, the caller should resolve the path to make sure we are locking the correct absolute path.
