Yes, they are classic logical optimization plus some Pig only
optimization. All these are rule based.
https://issues.apache.org/jira/browse/PIG-1319 is an umbrella Jira to
track all new optimization rules.

Hi,
I am also interested in this logical plan optimization framework
functionality. You mentioned that rules are being developed, could you
explain a little bit more about them? Are they like the classic logical
optimizations (early projection, early filtering, among others)?
Thanks in advance.

Thanks for the prompt reply. As you mentioned optimization is in its
developing stage, does it mean optimization framework is not complete or
only rules are in developing stage? In addition to that, I would really
appreciate if you could give a rough idea when the patch will be available
and what functionality will it contain?
At this point we believe the framework is complete and rules are being
developed. But the framework has never been used in user testing situations
(alpha or beta testing) so there will be a whole round of bugs to fix once
that testing is done.
The current plan is to switch to this code as the actual optimizer with
0.8, which we hope to release late this year (no promises).
