Optimizations in the Transform take the operator tree and transform that
into a new operator tree.
Then the operator tree is broken into various tasks.
Physical optimizer takes a task and optimizes/changes the task.
Both these optimizations are done at compile time.
There is nothing like a runti
Hello,
1) Does Hive consider a clear-cut distinction between compile-time
optimization and run-time optimization?
2) Does anybody know the difference between the optimizations implementing
the Transform and the ones implementing the PhysicalPlanResolver? Why such
optimizations are they in separate
