Feed: Planet PostgreSQL. Posted on Aug 22, 2018 at 14:39. Tags: conferences, fosdem, postgresql, pgconfeu, stockholm, prague, tokyo, san francisco, postgresopen, pgeu. Summer vacation times are over. Well, for some of us at least, clearly some are still lucky enough to be off, which is showing itself a bit (see below). But as both conference organisation and participation throughout the rest of the year is starting to be clear, I figure it's time to share some updates around different ones. Postgres Open SV First of all - if you haven't already, don't forget to register for Postgres Open SV in ... Read More

Feed: Planet MySQL; Author: Jean-François Gagné; Jean-François Gagné  | June 28, 2018 |  Posted In: MariaDB, MySQL PREVIOUS POSTMariaDB 10.3 is now generally available (10.3.7 was released GA on 2018-05-25). The article What’s New in MariaDB Server 10.3 by the MariaDB Corporation lists three key improvements in 10.3: temporal data processing, Oracle compatibility features, and purpose-built storage engines. Even if I am excited about MyRocks and curious on Spider, I am also very interested in less flashy but still very important changes that make running the database in production easier. This post describes such improvement: no InnoDB Buffer Pool in core dumps.Hidden ... Read More

Feed: Planet PostgreSQL. Last week I’ve presented my “PostgreSQL Standard SQL Gap Analysis” at PGCon.org in Ottawa. If this sound familiar you might confuse it with the opposite talk “Features Where PostgreSQL Beats its Competitors” I gave at FOSDEM and PgConf.de this year.The abstract of the gap analysis:PostgreSQL supports an impressive number of standard SQL features in an outstanding quality. Yet there remain some cases where other databases exceed PostgreSQL’s capabilities in regard to standard SQL conformance.This session presents the gaps found during an in-depth comparison of selected standard SQL features among six popular SQL databases. The selected features include, ... Read More

Feed: Planet MySQL; Author: Jean-François Gagné; I am now in an airport, waiting for one of the four flights that will bring me to Percona Live Santa Clara 2018.  This is a good time to write some details about my tutorial on parallel replication.  But before talking about Percona Live, I will share thoughts on MySQL/MariaDB bugs that caught my attention in the last weeks/months (Valeriy: you clearly have an influence on me). MySQL/MariaDB bugs Bug#69223 (Give a warning on CREATE TABLE without PRIMARY KEY by Daniël van Eeden) was brought back to my attention by Daniël publishing an audit plugin for that ... Read More

Feed: Planet PostgreSQL. Last week, I was at Nordic PGDay 2018 and I had quite a few conversations about the tool that I wrote, namely pglupgrade, to automate PostgreSQL major version upgrades in a replication cluster setup. I was quite happy that it has been heard and some other people in different communities giving talks at meetups and other conferences about near-zero downtime upgrades using logical replication. Given that there is a talk that I gave at PGDAY’17 Russia, PGConf.EU 2017 in Warsaw and lastly at FOSDEM PGDay 2018 in Brussels, I thought it is better to create a blog post ... Read More

Feed: Planet MySQL; Author: Frederic Descamps; Prior to MySQL 8.0, MySQL was missing a very well know feature in other RDBMS: optimizer histograms. The Optimizer Team implemented this feature as more and more MySQL DBAs were requesting it. Definition But what are histograms ? For wikipedia, a histogram is an accurate representation of the distribution of numerical data. For RDBMS, a histogram is an approximation of the data distribution within a specific column. So in MySQL, histograms help the optimizer to find the most efficient Query Plan. Example To illustrate how histograms  influence the optimizer, I will use data from ... Read More
