Robert Haas: August 2014

http://rhaas.blogspot.com/2014_08_01_archive.html

VP, Chief Architect, Database Server @ EnterpriseDB, PostgreSQL Major Contributor and Committer. Wednesday, August 06, 2014. Database performance and hardware selection are complicated topics, and a great deal has been written on that topic over the years by many very smart people, like Greg Smith, who wrote a whole book about PostgreSQL performance. 160; In many cases, the answers to performance questions require deep understanding of software and hardware characteristics and careful study and planning.

Robert Haas: Parallelism Update

http://rhaas.blogspot.com/2014/12/parallelism-update.html

VP, Chief Architect, Database Server @ EnterpriseDB, PostgreSQL Major Contributor and Committer. Monday, December 22, 2014. It's been over a year since I last blogged about parallelism. So I think I'm past due for an update, especially because some exciting things are happening. First, Amit Kapila has published a draft patch for parallel sequential scan. It shows a very substantial speed-up over a non-parallel sequential scan. So we're not there yet, but we're getting there. December 22, 2014 6:20 PM.

Robert Haas: PostgreSQL Shutdown

http://rhaas.blogspot.com/2015/03/postgresql-shutdown.html

VP, Chief Architect, Database Server @ EnterpriseDB, PostgreSQL Major Contributor and Committer. Tuesday, March 31, 2015. PostgreSQL has three shutdown modes: smart, fast, and immediate. For many years, the default has been "smart", but Bruce Momjian has just committed a patch. To change the default to "fast" for PostgreSQL 9.5. In my opinion, this is a good thing; I have complained about the current, and agreed with others complaining about it, many times, at least as far back as December of 2010. The f...

Robert Haas: Parallel Sequential Scan for PostgreSQL 9.5

http://rhaas.blogspot.com/2015/03/parallel-sequential-scan-for-postgresql.html

VP, Chief Architect, Database Server @ EnterpriseDB, PostgreSQL Major Contributor and Committer. Wednesday, March 18, 2015. Parallel Sequential Scan for PostgreSQL 9.5. Currently, if you'd like to test out parallel sequential scan, you need to look at four different patches. Most of these patches are being updated at a rather brisk pace, so by the time you read this the versions mentioned here may no longer be the latest ones. But right now, I think the latest versions are:. Parallel seqscan v10.patch.

Robert Haas: Linux's fsync() woes are getting some attention

http://rhaas.blogspot.com/2014/03/linuxs-fsync-woes-are-getting-some.html

VP, Chief Architect, Database Server @ EnterpriseDB, PostgreSQL Major Contributor and Committer. Monday, March 10, 2014. Linux's fsync() woes are getting some attention. In two weeks, I'm headed to LSF/MM. And the Linux Collaboration Summit. By invitation of some Linux kernel hackers, to discuss how the Linux kernel can better interoperate with PostgreSQL. This is good news for PostgreSQL, and hopefully for Linux as well. A post from Mel Gorman. March 10, 2014 5:49 PM. March 10, 2014 5:49 PM. If you are ...

About Open Source databases and supporting tools. Thursday, June 5, 2014. Utilising caching contrib's pg prewarm and pg hibernator in PostgreSQL 9.4. Numerous DBA's (counting me), put questions all the time to PostgreSQL hackers/developers/architects on mailing list:. Q1 Does PG has the ability to cache/warm a relation? Q2 Is it possible to return to prior state of cache where it was left before shutting down the database server because of maintenance? Contrib (Author: Robert Haas. Let's put all these co...
