> 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.
