This post continues from my report on Random Numbers. I have begun working on a random data generator so I want to run some tests to see whether different random number generators actually impact the overall performance of a data generator. Let’s say we want to create random data for a table with 17 columns, […]
Postgres BDR has seen exciting growth in the financial services and telecommunication industries. These industries present a new set of challenges that push the limits of Postgres Synchronous COMMIT features for Highly Available clusters. This webinar explored the Postgres Synchronous COMMIT deployment models and discussed the limitations associated with them. The webinar also introduced a […]
Welcome to the third – and last – part of this blog series, exploring how the PostgreSQL performance evolved over the years. The first part looked at OLTP workloads, represented by pgbench tests. The second part looked at analytical / BI queries, using a subset of the traditional TPC-H benchmark (essentially a portion of the […]
I’ve been slowly working on developing open source database systems performance testing tools from scratch. One of the components of this toolset is a data generator that can build a dataset to be loaded into a database. I’ll need a random number generator for that and these are the requirements that I think are most […]
Postgres is a great database engine but what are the best ways to load data into it? In order to explore Bulk Data Loading in PostgreSQL in detail, 2ndQuadrant arranged a live webinar, “Best Practices for Bulk Data Loading in PostgreSQL", which explored the answers to some of the most common questions related to bulk data loading: […]
This webinar on PostgreSQL Partitioning (originally conducted in 2019), is now available to watch on our YouTube channel. This webinar gave an overview of PostgreSQL partitioning and how it plays a key role in sensible management and improved performance with very large databases. Particular use cases were also highlighted, along with taking a look at […]
In the first part of this blog series, I’ve presented a couple of benchmark results showing how PostgreSQL OLTP performance changed since 8.3, released in 2008. In this part I plan to do the same thing but for analytical / BI queries, processing large amounts of data. There’s a number of industry benchmarks for testing […]
OmniDB is an effective workspace to tame and optimize PostgreSQL clusters, with easy and secure access to data, system health, and customizations. And all this, unified in the flavor of your preference: web-browser solution with access to multiple DBAs or a single ready-to-use desktop app installed on your working station. In order to explore OmniDB […]
A couple years ago (at the pgconf.eu 2014 in Madrid) I presented a talk called “Performance Archaeology” which showed how performance changed in recent PostgreSQL releases. I did that talk as I think the long-term view is interesting and may give us insights that may be very valuable. For people who actually work on PostgreSQL […]
In the past, major upgrades of terabyte size PostgreSQL databases required extended downtime or great amounts of work. With logical decoding, a whole new world of opportunities appeared for upgrades that require a very small amount of downtime. This webinar gave a comprehensive overview of how to perform a “near” zero downtime upgrade using pglogical, […]
