Hi all,
I'm interested in this parallel project,
http://wiki.postgresql.org/wiki/Parallel_Query_Execution
But I can't find any discussion and current progress in the website, it
seems to stop for nearly a year?
Thanks,
Li Jie

Yeah, I don't know of anybody really working on it ATM.
If you are interested in a process based design, please have a look at
the bgworker infrastructure stuff. It could be of help for a
process-based implementation.

yes, i don't know of anybody either.
in addition to that it is more than a giant task. it means working on more than just one isolated part.
practically i cannot think of any stage of query execution which would not need some changes.
i don't see a feature like that within a realistic timeframe.
regards,
hans
