- e.g. Each vertex in Tez is a different process.
It is upto the Tez DAG planner to attend to such runtime optimization details.

Algorithm selection is not that different between
MR Tez (except for intermediate HDFS writes). So assume that CBO can support
both execution layers rather easily.
5. CBO framework allows you to plug and play any cost model. There is no hard
coupling.

in to trunk yet.
I need to remove some of the limitations (outer join, union) before it can go
on to trunk.
Also a better algorithm for join permutations is also being worked on.

.
This is a limited version that does not support:
1. Outer Joins
2. Union
3. All of the UDFs
4. Doesn't play all permutations of joins
