Hi Daniel, Thanks, but that was not what I was actually looking. What I want to know is for example, how the optimizer work when the bags' logical plans are combined, or if all commands are reduced at the end to CO-GROUP commands, how is this handled? I know from Pig's paper that the ORDER, and LOAD, commands generate new MapReduce jobs, are there any optimizations for the physical plans? Thanks in advanced.
