alluxio.master.predicate.TimePredicate.DateFromFileNameOlderThanFactory

All Implemented Interfaces:

FilePredicateFactory

Enclosing class:

TimePredicate

public static class TimePredicate.DateFromFileNameOlderThanFactory
extends Object
implements FilePredicateFactory

Factory for file name time predicate. This predicate needs a pattern from the user input to extract the date from the filename. For now, we support exact date format i.e. YYYY-MM-DD, /bin/usr/fileYYYY-MM-DD. YYYY represents the number of year. MM represents the number of month. DD represents the number of day. Later we will support more different patterns. For example, if the pattern is aaaaYYYYMMDD, it will extract date from aaaa20230304, aaaa2023030588999, bbbb20230304. A warning message will be thrown if the pattern is empty, or it does not include YYYY, MM and DD.
