“Isn’t it ironic that in 2016 a non-skilled user can find a web page from Google’s untold petabytes of data in millisecond time, but a highly trained SQL expert can’t do the same thing in a relational database one billionth the size?.–Jim Starkey.

I have interviewed Jim Starkey. A database legend, Jim’s career as an entrepreneur, architect, and innovator spans more than three decades of database history.

Q1. In your opinion, what are the most significant advances in databases in the last few years?

Jim Starkey: I’d have to say the “atom programming model” where a database is layered on a substrate of peer-to-peer replicating distributed objects rather than disk files. The atom programming model enables scalability, redundancy, high availability, and distribution not available in traditional, disk-based database …

This article demonstrates how MySQL sharding with ProxySQL works.

Recently a colleague of mine asked me to provide a simple example on how ProxySQL performs sharding.

In response, I’m writing this short tutorial in the hope it will illustrate ProxySQL’s sharding functionalities, and help people out there better understand how to use it.

ProxySQL is a very powerful platform that allows us to manipulate and manage our connections and queries in a simple but effective way. This article shows you how.

Before starting let’s clarify some basic concepts.

• ProxySQL organizes its internal set of servers in Host Groups (HG), and each HG can be associated with users and Query Rules (QR)
• Each QR can be final (apply = 1) or = let ProxySQL continue to parse other QRs
• A QR can be a rewrite action, be a simple match, have a specific target HG, or be generic
• QRs are defined …

In the previous blog post, we looked into Docker’s single-host networking for MySQL containers. This time, we are going to look into the basics of multi-host networking and Docker swarm mode, a built-in orchestration tool to manage containers across multiple hosts.

Docker Engine - Swarm Mode

Running MySQL containers on multiple hosts can get a bit more complex depending on the clustering technology you choose.

Before we try to run MySQL on containers + multi-host networking, we have to understand how the image works, how much resources to allocate (disk,memory,CPU), networking (the overlay network drivers - default, flannel, weave, etc) and fault tolerance (how is the container relocated, failed over and load balanced). Because all these will impact the overall operations, uptime and performance of the database. …

[something happened to this post and I am reposting it]
It was suggested by Monty that the posts I've made about MariaDB are for publicity. This simply isn't true. I would have much preferred a different outcome in my interactions with MariaDB. I figured that they would end up giving me a hard time, and I'd be stubborn and we'd both hate each other for as long as I could keep from leaving. A quick separation actually seems much better in such context. Regardless, I would have preferred to speak amicably to the MariaDB Corporation about switching the license back, or at least moving to the new license at the time of the notification of the community, ie, changing the license so that bug fixes for 1.3.4 were not mingled with new 2.0 features.

It could have been easily possible to have a 1.3.5 release that fixes the major bugs in 1.3 and then release a new set of features as 2.0. This would have been at least reasonable, but by …

OPEN SOURCE IS ABOUT BEING OPEN NOT JUST ABOUT SOURCE CODE.
MariaDB makes changes to the storage engine API without even consulting the mailing list. In fact, some MariaDB replication features don't work with TokuDB because a new storage engine API call is required, and this call requires functionality that might not exist in all engines, that is, the engine must be able to convert a transaction id into a THD object. No API is provided by the SE to make this translation. MariaDB must communicate changes to the storage API to the public so that the public can ensure that tools made to work with MariaDB continue to work with MariaDB. It doesn't matter that TokuDB is made by a competitor. In a foreign language article, Kaj recently said MariaDB is more open than Oracle because it includes many storage engines. This is a crappy argument. MariaDB is trying to say they are better than Oracle because they profit more from including code they didn't …

Calling all Bostonian MySQL professionals, experts, amateurs, and enthusiasts! On October 10, Baron Schwartz, VividCortex's founder and CEO, will join the Boston MySQL Meetup Group for a presentation titled "Meeting the Challenges of Monitoring in the Cloud."

As DBaaS and "serverless" systems increasingly underlie the current paradigm for app development, understanding the best ways to gain visibility into cloud-based systems is becoming ever more important. Between Baron's experience building VividCortex, a cloud-based database peformance management platform, and writing about best practices for database performance and scaling, he has a unique perspective for leading an insightful and interactive conversation about the current challenges of monitoring in the cloud -- and what those challenges might look like in the …
