org.apache.hudi.hadoop.fs

Class CachingPath

java.lang.Object

org.apache.hadoop.fs.Path

org.apache.hudi.hadoop.fs.CachingPath

All Implemented Interfaces:

Comparable

@ThreadSafe
public class CachingPath
extends org.apache.hadoop.fs.Path

This is an extension of the Path class allowing to avoid repetitive computations (like getFileName, toString) which are secured by its immutability NOTE: This class is thread-safe

static CachingPath	concatPathUnsafe(org.apache.hadoop.fs.Path basePath, String relativePath)
static CachingPath	createRelativePathUnsafe(String relativePath) Creates path based on the provided *relative* path NOTE: This is an unsafe version that is relying on the fact that the caller is aware what they are doing this is not going to work with paths having scheme (which require parsing) and is only meant to work w/ relative paths in a few specific cases.
