Description

We need a mechanism to pass the lineage information of the various columns of a table to a pre execution hook so that applications can use that for:

auditing
dependency checking

and many other applications.

The proposal is to expose this through a bunch of classes to the pre execution hook interface to the clients and put in the necessary transformation logic in the optimizer to generate this information.
