Olga Natkovich commented on PIG-30:
-----------------------------------

A couple of other issues I observed with BigDataBag:

- Should check memory availability periodically, not on every add
- Try to buffer in memory first. Currently we always write to disk after the first spill

> We should never use DataBag directly; instead, we should always use BigDataBag. I think we already do this. The problem is that the logic in BigDataBag is hard to follow and it is made more complicated because it subclasses DataBag. We should merge these two classes together.
