Motivation Melbourne just won the “most liveable city 2016”, the 5th time in a row. That’s awesome, but it comes with a price, and the one you’d think of: internet here sucks! Sounds weird, isn’t it? Well, one of the reasons Melbourne is such a great city, is it’s size, the amount of people in [...]

Thank you for attending my 22nd July 2016 webinar titled “Top Most Overlooked MySQL Performance Optimizations“. In this blog, I will provide answers to the Q & A for that webinar.

For hardware, which disk raid level do you suggest? Is raid5 suggested performance-wise and data-integrity-wise?
RAID 5 comes with high overhead, as each write turns into a sequence of four physical I/O operations, two reads and two writes. We know that RAID 5s have some write penalty, and it could affect the performance on spindle disks. In most cases, we advise using alternative RAID levels. Use RAID 5 when disk capacity is more important than performance (e.g., archive databases that …

I know this is a tad late, but there have been some changes, etc. recently, so apologies for the delay of this post. I still hope to meet many of you to chat about MySQL/Percona Server/MariaDB Server, MongoDB, open source databases, and open source in general in the remainder of August 2016.

• LinuxCon+ContainerCon North America – August 22-24 2016 – Westin Harbour Castle, Toronto, Canada – I’ll be speaking about lessons one can learn from database failures and enjoying the spectacle that is the 25th anniversary of Linux!
• Chicago MySQL Meetup Group – August 29 2016 – Vivid Seats, Chicago, IL – more lessons from database failures here, and I’m looking forward to meeting users, etc. in the Chicago area

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.…

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!

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 …
