PostgreSQL Award

July 23, 2019 /0 Comments/in Mark's PlanetPostgreSQL /by Mark Wong

PostgreSQL was presented with the 2019 O’Reilly Open Source Award for Lifetime Achievement in Portland, Oregon, Thursday July 18th during OSCON. I had the honor of accepting that award alongside Bruce Momjian and Christophe Pettus. Starting last year in 2018, these awards were presented to projects and the first Lifetime Achievement award was given to […]

Visualizing sar data

June 1, 2017 /1 Comment/in Mark's PlanetPostgreSQL /by Mark Wong

Hopefully you are now regularly collecting system statistics after reading Tomas Vondra’s defense of using sar.  If you don’t have anything in place that readily visualizes the data, I have some examples that you can hopefully build off on to see everything you need to see. In addition to sar, the sysstat package also has […]

SCALE 14x

January 25, 2016 /2 Comments/in Mark's PlanetPostgreSQL /by Mark Wong

I had the pleasure of speaking about PostgreSQL performance at The 14th Annual Southern California Linux Expo and meeting many enthusiastic database users in the expo hall. There was a great turnout of people attending the conference, and many PostgreSQL presentations to see. Simon Riggs also talked about SERIALIZABLE, Eventual Consistency and Really Scary Stuff. […]

Testing Postgres-XL with DBT-3

October 8, 2015 /6 Comments/in Mark's PlanetPostgreSQL /by Mark Wong

As people have been working on merging Postgres-XL with the PostgreSQL 9.5 branch, I’ve been trying out Postgres-XL’s ability to run a decision support-like workload.  The DBT-3 test kit, originally developed at the OSDL as a TPC-H derivative, has some new changes so that it can run against Postgres-XL. I’ll describe how to use DBT-3 […]

Index Overhead on a Growing Table

October 10, 2014 /0 Comments/in Mark's PlanetPostgreSQL /by Mark Wong

This another simple test in continuation from last time. We will start with the same lineitem table as in the previous example. We will measure the time it takes to load the same 7.2GB text file repeatedly until the table size grows to about 1TB. We create a baseline with a table that has no indexes built on […]

Loading Tables and Creating B-tree and Block Range Indexes

October 3, 2014 /2 Comments/in Mark's PlanetPostgreSQL /by Mark Wong

I have been looking at the new Block Range Indexes (BRIN) being developed for PostgreSQL 9.5. BRIN indexes are designed to provide similar benefits to partitioning, especially for large tables, just without the need to declare partitions. That sounds pretty good but let’s look in greater detail to see if it lives up to the hype. How large? Here’s […]
