Subject [jira] [Commented] (CRUNCH-420) Breakpoints Not Working
Date Mon, 16 Jun 2014 13:26:01 GMT


Gabriel Reid commented on CRUNCH-420:

Ok, that now fully refreshes my memory on the subject (as well as being in line with what
I saw in the code, unsurprisingly).

>From what I've seen in the code a slightly simpler version of the inter-GBK edge splitting
can be done to handle this situation as well. My thinking is that any edge that ends in a
materialization output could be dropped in as a replacement for the first portion of other
edges that start from the same vertex and have a NodePath that is a superset of the materialization
NodePath -- does that make sense?

> Reading through CRUNCH-294, it looks like materialize is supposed to function as a breakpoint
to the planner. I've seen several plans where it appeared to me a particular DoFn shouldn't
have been repeated, but it was.
> I'll attach some supporting material.
