[Pig-dev] Pig Server API

I have a couple of questions on some of the public methods that Pig
Server exposes:



* Update functions: these functions (two of them) are classified
in the marked in comments as the "continuous version" of the store
function. I am not sure what that means. Is this work related to some
changes that pertain to incremental Pig and that made it to the main
branch of the code? Utkarsh, maybe you can help me with this?



* Functions newRelation and insertTuple: looks like these
functions are not documented and I am wondering what applications are
using them?



Thanks,
