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
> Get rid of DataBag and always use BigDataBag

> 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.
