Interface PathConfiguration

All Known Implementing Classes:

PrefixPathConfiguration

public interface PathConfiguration

Path level configuration. An AlluxioConfiguration is set for each path pattern. This class matches an Alluxio path against the patterns, then from the configurations of the matched patterns, it chooses the configuration that contains the specified property key and belongs to the best matched pattern. Different implementations have different definitions of the best match.
