All Implemented Interfaces:

org.apache.accumulo.core.iterators.OptionDescriber, org.apache.accumulo.core.iterators.SortedKeyValueIterator<org.apache.accumulo.core.data.Key,org.apache.accumulo.core.data.Value>

public class MetadataExpirationFilter
extends ExpirationFilter

Allows Accumulo to expire keys/values based on an expiration threshold encoded in a metadata map in the value.
