MySQL 5.7 makes secure connections easier with streamlined key generation for both MySQL Community and MySQL Enterprise, improves security by expanding support for TLSv1.1 and TLSv1.2, and helps administrators assess whether clients are connecting securely or not with new visibility into connection types. …

What about an hackathon to fix several issues in Innotop during this Fosdem 2016 edition ?

As the MySQL & Friends Devroom is on Saturday, Sunday would be the perfect day to find a nice place in the bar and work on resolving the open issues in Innotop to support MariaDB 10.1, MySQL 5.7…

If you are interested just send me a tweet (@lefred) and we can arrange this meeting.

I recently worked a lot on getting my local Windows box to compile Windows.
I got a lot of help from the below link that took me a few steps towards the
solution.
http://www.chriscalender.com/resolving-the-bison-exe-m4-invalid-argument-error-when-building-mysqlmariadbxtradb-on-windows/

I had to save away my bison installation, uninstall it and then also
go into a registry editor and remove the various links to the Start Menu referring to
some help for Bison that had spaces in the registry. Resolving this meant that I could
manually run bison on the files in the mysql tarball and get the desired result. But it
was still not enough, I still had the same error when running a full automatic compile.

So then I found the …

Back in October I have write about possible ways of running multiple MySQL instances on the same hardware. As the months passing by, the project of splitting our database schemas into standalone instances is closing in, so I started to check the different ways.

EDIT: This post is outdated, here is the follow up.

I started with docker, because we’ll use containers anyway with the applications, and I think it is a good idea to minimise the diversity of an infrastructure. I used the docker’s “official” Percona image (it is official by Docker not by Percona!) which is easy to use, and flexible enough. (https://hub.docker.com/_/percona/) This image supports using custom config files, you can mount your …

A modern MySQL server contains a lot of useful meta-data in information_schema and performance_schema, which can help bring visibility into what is happening inside of your database server. However, sometimes this data is quite fine grained and needs finessing in order to get to that point

MySQL 5.7 includes a new SYS schema installed by default.…

Over several previous blog posts, we’ve already discussed what information the 

EXPLAIN FORMAT=JSON

 output provides for some subqueries. You can review those discussions here, here and here. EXPLAIN FORMAT=JSON shows many details that you can’t get with other commands. Let’s now finish this topic and discuss the output for the rest of the subquery types.

In February my colleague Morgan Tocker will travel through Europe and talk about MySQL 5.7, which recently went GA.

In Munich we're having a meeting for PHPers and other Web developers, where Morgan will talk about MySQL and JSON and I'll also be around.

Summary of the talk:

With the newly added JSON support in MySQL, you can combine the flexibility of NoSQL with the strength of a relational database. In this session, Morgan will explain the new JSON datatype, and the new set of functions for handling JSON documents, available storage and indexing options. In addition, he will present benchmarks showing how much one can expect from the MySQL server in different use case scenarios.

About Morgan: Morgan rejoined the MySQL team at Oracle in 2013 as MySQL Community Manager, having …

Percona invites you to attend a webinar Wednesday, January 27th, with CEO Peter Zaitsev: Compression In Open Source Databases. Register now!

Data growth has been tremendous in the last decade and shows no signs of stopping. To deal with this trend database technologies have implemented a number of approaches, and data compression is by far the most common and important. Compression in open source databases is complicated, and there are a lot of different approaches – each with their own implications.

In this talk we will perform a survey of compression in some of the most popular open source database engines including: Innodb, TokuDB, MongoDB, WiredTiger, RocksDB, and PostgreSQL.
