This ticket is implemented in d7aa989ee1c72d7830c612554b89673bf38cf447 > TupleSerializerBase.getLength should know the length when all fields know it > ---------------------------------------------------------------------------- > > Key: FLINK-3321 > URL: https://issues.apache.org/jira/browse/FLINK-3321 > Project: Flink > Issue Type: Improvement > Components: Java API > Reporter: Gabor Gevay > Assignee: Chesnay Schepler > Priority: Minor > Labels: starter > > TupleSerializerBase.getLength currently always returns -1, but it could > actually know the length, when all the field serializers know their lengths > (since no null can appear anywhere in Tuples, nor can a subclass of Tuple > with additional fields appear). > (The serializer knowing the exact size has various performance benefits, for > example see FixedLengthRecordSorter, or > CompactingHashTable.getInitialTableSize.) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
