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 […]
After I shared the sequential UUID benchmarks a couple of weeks ago, one of the points raised in feedback was the choice of the storage space. I’ve intentionally used a fairly weak storage system (RAID10 on three 7.2k SATA drives) because I wanted to demonstrate the benefits. But a couple of readers suggested using SSDs might significantly reduce […]
Since the release of v3, Postgres-BDR has evolved into the go-to clustering technology built specially for businesses that require geographically distributed databases with multiple masters. To get an update on Postgres-BDR’s development, new features, and future roadmap, 2ndQuadrant held the pglogical and Postgres-BDR Update webinar as part of its PostgreSQL webinar series. The webinar was […]
After the final release of patch 9.3.25 on November 8th 2018, PostgreSQL 9.3 is no longer supported. Therefore it’s time for all users of PG 9.3 to upgrade their databases to a newer supported version. The benefits of having a supported version are many and that’s what Craig Ringer talks about in the Q&A session […]
Let’s assume you have some sensitive data, that you need to protect by encryption. It might be credit card numbers (the usual example), social security numbers, or pretty much anything you consider sensitive. It does not matter if the encryption is mandated by a standard like PCI DSS or if you just decided to encrypt […]
A database management tool that simplifies what is complex and drives performance. OmniDB is one such tool with which you can connect to several different databases – including PostgreSQL, Oracle, MySQL and others. 2ndQuadrant recently hosted a webinar on this very topic: Introduction to OmniDB. The webinar was presented by OmniDB co-founders and PostgreSQL consultants […]
UUIDs are a popular identifier data type – they are unpredictable, and/or globally unique (or at least very unlikely to collide) and quite easy to generate. Traditional primary keys based on sequences won’t give you any of that, which makes them unsuitable for public identifiers, and UUIDs solve that pretty naturally. But there are disadvantages […]
PostgreSQL is referred to as “The world’s most advanced open source database” – but what does PostgreSQL have that other open source relational databases don’t? 2ndQuadrant recently hosted a webinar on this very topic: PostgreSQL is NOT your traditional SQL database, presented by Gülçin Yıldırım Jelínek, Cloud Services Manager at 2ndQuadrant. The recording of […]
During the PostgreSQL 11 development cycle an impressive amount of work was done to improve table partitioning. Table partitioning is a feature that has existed in PostgreSQL for quite a long time, but it really wasn’t until version 10 that it started to become a highly useful feature. We’d previously claimed that table inheritance was […]
In PostgreSQL version 10 or less, if you add a new column to a table without specifying a default value then no change is made to the actual values stored. Any existing row will just fill in a NULL for that column. But if you specify a default value, the entire table gets rewritten with […]
