With MySQL version 5.7.12 and up, Oracle continues to improve MySQL’s security features by adding MySQL Enterprise Transparent Data Encryption (TDE) for InnoDB tables stored in innodb_file_per_table tablespaces. This feature provides at-rest encryption for physical tablespace data files.

MySQL Enterprise TDE uses a two-tier encryption key architecture, consisting of a master encryption key and tablespace keys.…

MySQL 5.7/8.0 does not allow creating a full-text index on a JSON column. Although a full-text index would be useful – unstructured data deserves unstructured search. I am unaware o any workaround of this limitation that does not require storing the JSON data twice. Then I started messing around, allowed indexing of JSON columns, saw great execution times but eventually followed MySQLs’ decision to call it a day. Friday afternoon rambling on indexing and easy hacking…

Why full-text: JSON indexing limitations and pitfalls

The current version of the MySQL Document Store is not yet optimized for performance. When we started this effort, we quickly gathered a long list of features that we considered a must have prior to any serious performance tuning. The teams focussed building infrastructure and delivered many …

It is soon time for the annual Oracle OpenWorld conference in San Francisco. This year it takes place from 18 to 22 September. There will be a wide range of talks about MySQL and other Oracle products with speakers including Oracle developers, product management, Support, customers, and community members. So there should be something for everyone.

MySQL Support will have two talks this year:

Sequences are objects defined by the SQL standard that are used to create monotonically increasing sequences of numeric values. Whenever nextval is called on a sequence object, it generates and returns the next number in the sequence. For MySQL and MariaDB users, this might sound similar to MySQL’s AUTO_INCREMENT columns, but there are some differences: Sequences are defined by the ... Read More

The GA release of ProxySQL 1.2.1 is available. You can get it from https://github.com/sysown/proxysql/releases. There are also Docker images for Release 1.2.1: https://hub.docker.com/r/percona/proxysql/.

ProxySQL is a high-performance proxy, currently for MySQL and its forks (like Percona Server and MariaDB). It acts as an intermediary for client requests seeking resources from the database. ProxySQL was created for DBAs by René Cannaò, as a means of solving complex replication topology issues.

This post is published with René’s approval. René is busy implementing more new ProxySQL features, so I decided to make this announcement!

This guide explains how to password-protect web directories (with users from a MySQL database) with mod_authn_dbd on Apache2 on a Debian 8 (Jessie) server. It is an alternative to the plain-text password files provided by mod_auth and allows you to use normal SQL syntax to create/modify delete users.

With SQLyog MySQL GUI 12.2.5, JSON comes to SQLyog. This is a new and major thing.  Also, Foreign Key management with NDB tables was added and the user- filter was improved in the User Manager. Additionally, some non-critical GUI bugs were fixed.

Changes as compared to MySQL GUI 12.2.4 include:

Features:

* Added basic support for the JSON datatype as of MySQL 5.7.8+ and MySQL Cluster 7.5.2+. The datatype is now available in the CREATE/ALTER TABLE dialog and JSON data will open in the BLOB-viewer. In the BLOB-viewer we have added validation that content is valid JSON. Also JSON-related keywords and functions are recognized in syntax highlighting and autocomplete. Also please see note at the bottom.
* SQLyog GUI now supports Foreign Key constraints between NDB tables for MySQL Cluster 7.3+.
* It is now possible to filter the users based on a string in the …

Introduction

A couple of months ago I decided to give myself a refresher on the mechanics of InnoDB. Having a high level understanding of what’s going on under the hood can help provide the context needed in order to resolve issues you may encounter as well as assist you in ensuring that your MySQL instance is running efficiently. Everyone can stand to go back to basics every now and then, as it can help you pick up concepts that you may have missed the last time you researched the topic.

This time around I decided to give myself a refresher by re-reading the MySQL 5.6 reference manual, chapter 14, which covers the InnoDB engine. Despite having a wealth of documented knowledge and insights, I found that a lot of the points in the documentations were unclear, leading me to do more research and experimentation in order to get a bit of clarity on some of the specifics that I felt were missing. In order to help make the information …
