-----------------------------------
Summary: Add ascending order option to builtin TOP function
Key: PIG-4062
URL: https://issues.apache.org/jira/browse/PIG-4062
Project: Pig
Issue Type: Improvement
Reporter: Ritesh Agrawal
Priority: Minor
Builtin TOP function orders records in descending order. However in lot of
cases you might want to get top N records in ascending order, such as when
ordering records by rank, etc. The idea is to extend the TOP function so that
it can be configured via DEFINE statement. For example
DEFINE TOPASC TOP("ASC");
To keep it backward compatible, the top function by default will continue to
order in descending order.
