-------------------------------------
Also I did not find any instance of S3 in the code. Perhaps you just mentioned
it for completeness but in case you do find an instance please let me know the
offending file.

> 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.
