--------------------------------------
Summary: Lazily register bags with SpillableMemoryManager
Key: PIG-2923
URL: https://issues.apache.org/jira/browse/PIG-2923
Project: Pig
Issue Type: Improvement
Reporter: Dmitriy V. Ryaboy
Currently, all Spillable DataBags get registered by the BagFactory at the
moment of creation. In practice, a lot of these bags will not get large enough
to be worth spilling; we can avoid a lot of memory overhead and cheapen the
process of finding a bag to spill when we do need it, by allowing Bags
themselves to register when they grow to some respectable threshold.
