---------------------------------------
Summary: Remove schema tuple reference overhead for replicate join
hashmap
Key: PIG-4874
URL: https://issues.apache.org/jira/browse/PIG-4874
Project: Pig
Issue Type: Improvement
Reporter: Rohini Palaniswamy
Assignee: Rohini Palaniswamy
Fix For: 0.16.0
Currently even if pig.schematuple is set to false which is the default, the
usage of TupleToMapKey and TuplesToSchemaTupleList instead of plain
HashMap<Object, ArrayList<Tuple>> costs a lot of memory. Also key is currently
converted to a tuple which is unnecessary.
