Sylvia Botros, Sendgrid’s lead DBA, recently told us about one of the ways her teams have found unique value in VividCortex. “Engineering managers and individual developers have pinged me and said, ‘Hey, I saw this in VividCortex -- what do you think?’ Some of our developers are not fully familiar with the generals of MySQL,” she explained, “but VividCortex is giving them a view into how their app is dealing with databases. And at the same time it’s teaching them DB lingo, which is good.”  

This feedback from Sylvia opens the door to one of the questions we hear a lot about VividCortex: “How is your solution different from my existing APM (Application Performance Management) tool?”It’s a great question with many technical answers, but ultimately the only answers that matter are the ones focused on results. As an engineering-led company, we’re …

MySQL Cluster is designed to provide a MySQL compatible database with high availability and low latency. The MySQL Cluster technology is implemented through the NDB (Network DataBase) and NDBCLUSTER storage engines and provides shared-nothing clustering and auto-sharding for MySQL database systems. In the shared-nothing architecture, each of nodes has its own memory and disk, the use of shared storage such as NFS, SANs is not recommended and supported.

Last time this blog covered digging into a JSON document in a MySQL 5.7 table. The goal was to pull certain records matching a particular criteria. Both Peter Zaitsev and Morgan Tocker get my thanks for their kind comments. My example was a little contrived in that an application would be used to fine tune seeking for a particular key value pair. I was trying to pull single records which is kind of silly when it is much easier to use PHP to parse the data. What follows below is a sample PHP script to grab out the matching records and then feed the results, the JSON document, into an array.

#!/usr/bin/php
<?php
$mysqli = new mysqli("localhost", "root", "hidave", "test");

/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", …

This is the first in a series of posts about the MySQL JSON data type, how it compares to working with a document-oriented store like MongoDB, and how we can make use of it in the Laravel framework.

• Part 1 is a quick look at the data type itself, and some of the functions available to work with that data. Specifically, we’ll focus on what kind of data to store and how to work with it, regardless of framework.

• In Part 2 we’ll walk through which MongoDB patterns can be replicated in MySQL with the JSON type, as well as what can’t. We’ll also check out some alternative strategies for document-oriented storage using MySQL as a backing store.

• Lastly, Part 3 will focus on using the JSON data type in Laravel applications, what contexts it is best suited for, and I’ll take a stab at some simple code you can use to …

The MySQL User Conference has a been fixture in all our calendars for many years now and every year, Santa Clara calls us back … The conference has evolved of course since its inception and yet stays the same, its original premise alive and kicking: a place to get together and exchange on MySQL and open source database knowledge and experiences! And today it’s called the Percona Live Data Performance Conference!

This year, the conference is really opening itself up to become inclusive of not only MySQL-related technologies and topics and go wide into MongoDB and Big Data territories as well. So there should be something new for everyone who’ll be attending and the programme looks quite promising indeed.

As in the previous two years, our team will be providing the necessary 9s for this year’s conference in the form of two talks and a …

InnoDB in MySQL 5.7 introduced for the first time the ability to create a general tablespace and assign multiple tables to it.  These tablespaces can be assigned anywhere on the system.  They can even be assigned a smaller block size so that they can contain compressed tables that use that size as their key_block_size.…
