Improving memory efficiency of Tuple implementation
---------------------------------------------------
Key: PIG-793
URL: https://issues.apache.org/jira/browse/PIG-793
Project: Pig
Issue Type: Improvement
Reporter: Olga Natkovich
Currently, our tuple is a real pig and uses a lot of extra memory.
There are several places where we can improve memory efficiency:
(1) Laying out memory for the fields rather than using java objects since since
each object for a numeric field takes 16 bytes
(2) For the cases where we know the schema using Java arrays rather than
ArrayList.
There might be more.
