Subject [FYI] recreation of the DAG-execplan branch
Date Fri, 18 Apr 2014 07:18:48 GMT
Hi folks.

We are improving the query plan by changing from the tree form to the DAG

The DAG form of query enables various query optimizations such as
intermediate result sharing or optimization for input correlation.

This work have been proceeded in the DAG-execplan branch, but updates get
too stale.
If we proceed more works, it needs numerous updates from the master branch
and causes a bunch of conflicts.
Thus, it would be better to recreate a new branch from the master branch to
include the necessary changes of the existing branch.

I hope that it will not make you confused.

Best regards,
