MySQL at Oracle Open World 2016

MySQL is a growing presence at Oracle Open World. While most of the headlines belong to the main products, where Oracle services are aiming at world domination, MySQL shared the spotlight, as it was announced to be part of Oracle database cloud. It seems a logical move for Oracle: after all the effort to make MySQL 5.7 the biggest release ever, it stands to reason that it is offered as a competitive feature in its own database as a service.

With this offer, Oracle is applying enterprise pricing and methodologies to a target of emerging companies. MySQL in the Oracle cloud differs from the competition by a few key points:

  • It's only MySQL 5.7. While this is the most advanced MySQL server …

Fun with Bugs #39 - Known Bugs in MySQL 5.7.9 GA

These days everybody is excited with recent announcement of MySQL 5.7.9 GA release. If you are not aware of this event yet (I've noted it from numerous posts even during my short vacation), wait for the Oracle Open World 2015 to begin tomorrow to announce it even wider and louder!

I already have 5.7.9 built from source, up and running, so it's time to check what else we can expect from this new GA release besides new great features (this is a topic for a separate post or two) and usual excitement. Yes, I mean known, verified bugs in MySQL 5.7.9.

Let me start with a quick summary and then present the details. So, even though MySQL Community tried hard to check 5.7.x at early stages and report bugs to Oracle, MySQL 5.7.9 GA has a number of known …

Fun with Bugs #26 - MySQL bugs Oracle had not fixed for me (yet)

In the previous post in this series I've listed 15 MySQL bug reports, documentation and feature requests I've made in 2013 that got fixes or any other kind of solution. Now it's time to check what happened to the rest and try to think why.

First of all, no MySQL bug reporter is perfect (if only Domas), so some bug reports may be false alarms ("Not a bug"), to hard to fix at any foreseeable future ("To be fixed later") or asking for something that Oracle does not plan to provide …

My Favorite Hidden Docs Page

There’s a lot to love about the MySQL product documentation – a lot of hard work from a number of very talented Oracle staff goes into it (not to mention the helpful suggestions and feedback from the community).  There is, however, one page I find myself coming back to again and again, despite the fact that it’s somewhat hard to find.  This is the MySQL Server options/variable reference page.  It’s a helpful table that lists every MySQL Server option or variable, what version it was introduced or deprecated in, whether it’s dynamic or not, whether variables have session/global/both scope, and links to the version-specific documentation for that variable (useful to know when default values changed, for example).

It always takes me a while to find this page again when I’m looking for it, as it’s …

Tungsten Replicator Filters: A trove of golden secrets unveiled

Since I joined the company in late 2010, I have known that one of the strong points of Tungsten Replicator is its ability of setting filters. The amazing capabilities offered by Tungsten filters cannot be fully grasped unless we explain how stage replication works.

There are several default stages in the replication stream. Every stage has an extraction task and an apply task. The extraction task will get data from the previous step repository and the apply task will save the data to the next repository, which can be either a temporary storage (memory queue, THL file) or the final destination (slave database server). Consider that the architecture allows developers to add stages, and you will appreciate its full power. For every stage, we can insert one or more filter between the two tasks. …

tpm, the multi-master composer

Multi master topologies blues

Tungsten Replicator is a powerful replication engine that, in addition to providing the same features as MySQL Replication, can also create several topologies, such as

  • all-masters: every master in the deployment is a master, and all nodes are connected point-to-point, so that there is no single point of failure (SPOF).
  • fan-in: Several masters can replicate into a single slave;
  • star: It’s an all-masters topology, where one node acts as hub which simplifies the deployment at the price of creating a SPOF.

The real weakness of these topologies is that they don’t come together easily. Installation requires several commands, and running them unassisted is a daunting task. Some time ago, we introduced a set of scripts (the Tungsten Cookbook) that allow you to install multi-master topologies with a …

Welcome Tungsten Replicator 2.1.0!


Overview

First off, the important news. Tungsten Replicator 2.1.0 was released today.
You can download it and give it a try right now.


Second, I would say that I am quite surprised at how much we have done in this release. The previous release (2.0.7) was in February, which is just a few months ago, and yet it looks like ages when I see the list of improvements, new features and bug fixes in the Release Notes. I did not realized it until I ran my last batch of checks to test the upgrade from the previous release, which I hadn’t run for quite a long time. It’s …
