--------------------------------------
Summary: Avoid Spillable bag overhead where possible
Key: PIG-2918
URL: https://issues.apache.org/jira/browse/PIG-2918
Project: Pig
Issue Type: Bug
Reporter: Dmitriy V. Ryaboy
We use BagFactory.newDefaultBag() liberally, and pay a price -- each such bag
registers with the spillable memory manager, and if we allocate a lot of tiny
bags, we wind up paying for maintaining and cleaning up the internal linked
list of weak references.
In many cases, we know a-priori that the bags are smal, and should probably be
creating non-spillable bags for those cases.
