Thread: Draft of Alpha release announcement
All: This goes out Thursday, so I'm putting it here for final comments/corrections. Sorry for the last-minute nature of this, but time kind of got away from me. I've added a new "what to test" section to get people thinking. We should create a more expanded version of this on the wiki for 9.5beta1, but for now, what do people think? -- Josh Berkus PostgreSQL Experts Inc. http://pgexperts.com

The contention around spinlocks has hit a lot of people over the last few years. Greetings, Andres Freund

If necessary, can you ping me in time to update the sgml?

I'm happy to write those up in Release Note format, but I was planning to wait until the Beta in case one or more features gets the axe before then. -- Josh Berkus PostgreSQL Experts Inc. http://pgexperts.com

The features are already in the release notes, and you're sending out the major features in the release announcement. Having an empty 'major enhancements' section in the release docs, linked to from the release announcement, is just confusing. Greetings, Andres Freund

I have a concern with this item: * Large speed improvements in in-memory sorting and hashing The largest acceleration that I've heard anyone have with the abbreviated keys sorting patch - a 12X improvement, reported by Corey Huinker - was actually with an external sort (in-memory sorts were more effectively accelerated during testing on my laptop, but Corey used a real server). I think that the "in-memory" qualifier does not add much information about the hashing improvements, and misleads about the sorting improvements. Too late for changing the 9.5 alpha notes now, but something to remember when the beta comes out. -- Regards, Peter Geoghegan
