Postgres-XL and global MVCC

April 2, 2019/0 Comments/in 2ndQuadrant, Koichi’s PlanetPostgreSQL, Postgres-XL /by Koichi Suzuki

Back to the PG I’m very excited to become a 2ndQuadrant member.  I was involved in PostgreSQL activities in NTT group (Japanese leading ICT company, see here and here), including log shipping replication and PostgreSQL scale out solution as PostgresXC and PostgresXL. At NTT I had several chances to work very closely with 2ndQuadrant.  After three years involvement in deep […]

pgxc_ctl: Teaching Postgres-XL in New York City

December 1, 2017/0 Comments/in 2ndQuadrant, Tom's PlanetPostgreSQL /by Tom Kincaid

At the 2ndQuadrant PostgreSQL conference in New York City this year, I had the pleasure of delivering a training on Postgres-XL together with Andrew Dunstan. We capped the attendees at 8 because we wanted to have a lot of lab time with the students and spend time helping them get set up with Postgres-XL. The class […]

Postgres-XL with OmniDB

October 17, 2017/1 Comment/in OmniDB, William's PlanetPostgreSQL /by William Ivanski

1. Introduction Postgres-XL (or just XL, for short) is an open source project from 2ndQuadrant. It is a massively parallel database built on top of PostgreSQL, and it is designed to be horizontally scalable and flexible enough to handle various workloads. Here we will show how to build a test environment to play with XL […]

News and Roadmap from Postgres-XL 10

July 5, 2017/6 Comments/in 2ndQuadrant, Pavan's PlanetPostgreSQL /by Pavan Deolasee

We expect Postgres-XL 10 to be released in the next few months, with the new features of partitioning and logical replication. You’ll be able to load Postgres-XL directly from PostgreSQL. For the first time, you’ll be able to run massively parallel queries both across the datanodes and within the datanodes to give huge performance gains. […]

Future of Postgres-XL

May 26, 2017/4 Comments/in PostgreSQL, Tomas' PlanetPostgreSQL /by Tomas Vondra

You probably know that Postgres-XL is a distributed database based on PostgreSQL. A few days ago we pushed the XL 9.6 code into the public git repository. Additional details about the new stuff available in Postgres-XL 9.6 are available here. The topic of this blog post is quite different, though. I’d like to discuss some […]

What’s new in Postgres-XL 9.6

May 12, 2017/3 Comments/in 2ndQuadrant, PostgreSQL, Tomas' PlanetPostgreSQL /by Tomas Vondra

For the last few months, we at 2ndQuadrant have been working on merging PostgreSQL 9.6 into Postgres-XL, which turned out to be quite challenging for various reasons, and took more time than initially planned due to several invasive upstream changes. If you’re interested, look at the official repository here (look at the “master” branch for […]

Postgres-XL Scalability for Loading Data

October 24, 2016/2 Comments/in Pavan's PlanetPostgreSQL /by Pavan Deolasee

In my last blog, we looked at the benchmark results from bulk load test for a Postgres-XL database cluster. Using a 16-datanode, 2-coordinator cluster, running on EC2 instances, we could easily clock 9M rows/sec or 3TB/hr of ingestion rate. That’s a significant number in itself. In this blog, we’ll see if the ingestion rate is […]

Load data in Postgres-XL at over 9M rows/sec

October 13, 2016/6 Comments/in 2ndQuadrant, Pavan's PlanetPostgreSQL /by Pavan Deolasee

We are faced with this question: “What’s the ingestion rate of Postgres-XL?”, and I realised I don’t have a very good answer to that. Since recently we made some good improvements in this area, I was curious to know too. Well, I decided to benchmark. Hardware and Software For the tests, I used a Postgres-XL cluster running […]

Postgres-XL 9.5r1.1 released

May 12, 2016/0 Comments/in 2ndQuadrant, Pavan's PlanetPostgreSQL /by Pavan Deolasee

The Postgres-XL community has released a new version of the software, tagged as 9.5r1.1. This is a minor update to earlier 9.5r1 release, but contains some very important bug fixes. I would encourage everyone to immediately upgrade to this latest release. Being a minor release, you only need to download the latest sources from , […]

Postgres-XL 9.5r1 has finally arrived!

April 18, 2016/2 Comments/in 2ndQuadrant, Pavan's PlanetPostgreSQL /by Pavan Deolasee

After months of efforts, I’m pleased that Postgres-XL 9.5r1 is seeing the daylight. It has been tremendous collective efforts by many, both inside and outside 2ndQuadrant. Often it’s not visible via commit history or mailing list communications, but I must admit that many folks have contributed in making this grand release. Contributors who wrote code […]
