Re: [HACKERS] [GSoC] Push-based query executor discussion
Sorry, I didn't notice that this was going to a public list. That URL is only available to people who signed up as mentors for PostgreSQL GSoC participation this year.

Re: [HACKERS] [GSoC] Push-based query executor discussion
Time is short, student's application deadline is on 3rd April. I decided to reformulate the project scope myself. Here is the proposal: https://docs.google.com/document/d/1dvBETE6IJA9AcXd11XJNPsF_VPcDhSjy7rlsxj262l8/edit?usp=sharing The main idea is that now there is a formalized goal of the project, "partial support of all TPC-H queries". I am also CC'ing people who was mentioned in "Potential Mentors" section on GSoC wiki page. -- Arseny Sher -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

Should we reject this interesting project, which based on several years of research work of academician group in the institute ? May be better help him to reformulate the scope of project and let him work ? I don't know exactly if the results of GSoC project should be committed , but as a research project it's certainly would be useful for the community. > > > -- > Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) > To make changes to your subscription: > http://www.postgresql.org/mailpref/pgsql-hackers >

I think that successfull completion of this project should be a clear and justified answer to the question "Is this idea is good enough to work on merging it into the master?", not the production-ready patches themselves.
