On April 5, 2018, the MySQL Workbench Team announced the first public release of version 8.0.11 as a Release Candidate (RC) together with MySQL Community Server 8.0.11. The first General Availability (GA) release appeared on July 27, 2018 again together with the server following the new policy for aligning version numbers across most of MySQL products. MySQL Workbench now uses ANTLR4 as backend parser and has a new auto-completion engine that works with object editors (triggers, views, stored procedures, and functions) in the visual SQL editor and in models. The new versions add support for new language features in MySQL 8.0, such as common-table expressions and roles. There's also support for invisible indexes and persisting of global system variables. The new default authentication plugin in MySQL 8.0 is now supported by Workbench, so resetting user accounts to other authentication types is no longer necessary when connecting to the latest servers. Administrative tabs are updated with the latest configuration options and the user interface was made more consistent between the tabs.
Starting with MySQL Workbench 5.2 the application has evolved to a general database GUI application. Apart from physical database modeling it features an SQL Editor, database migration tools, and a database server administration interface, replacing the old MySQL GUI Tools Bundle.
Part of the commercial MySQL Cluster CGE, MySQL Cluster Manager is a tool designed to simplify the creation and administration of the MySQL Cluster CGE database by automating common management tasks, including on-line scaling, upgrades, backup/restore and reconfiguration. MySQL Cluster Manager also monitors and automatically recovers MySQL Server application nodes and management nodes, as well as the MySQL Cluster data nodes.
On May 22, 2013, the MySQL Workbench Team announced that they were working on Version 6.0. The first public beta, labeled version 6.0.2, was released on June 14, 2013, and the first general-availability release was made on August 12, 2013.
On March 5, 2015, the MySQL Workbench Team announced its first public beta release of Version 6.3. The first general-availability release was made on April 23, 2015. New features include a "fast migration" option to migrate the data from the command-line instead of the GUI, a SSL certificate generator, improved SQL auto-completion, a new table data import and export wizard, and MySQL Enterprise Firewall support. Version 6.3.8, MySQL Workbench for MacOS has incompatibilities with MacOS Sierra. Version 6.3.9 is compatible with MacOS Sierra, however it doesn't work on MacOS High Sierra. MacOS High Sierra users need to run version 6.3.10.
On January 23, 2014 the MySQL Workbench Team announced its first public beta release of Version 6.1. The first general-availability release was made on March 31, 2014. New features include improved Visual Explain output, a Performance dashboard, Performance Schema support, additional query result views, and MSAA support.
On August 19, 2014, the MySQL Workbench Team announced its first public beta release of Version 6.2. The first general-availability release was made on September 23, 2014. New features are shortcut buttons for common operations, "pinning" of the results tab, Microsoft Access Migration, MySQL Fabric Integration, Spatial View Panel to visualize spatial and geometry data, Geometry Data Viewer, Result Set Width, SQL editor tabs are properly saved, Shared Snippets, a new Run SQL Script dialog, Model Script Attachments, Client Connections management has a new "Show Details" window where more information about connections, locks, and attributes is displayed, performance columns can display sizes in KB, MB, or GB, the migration wizard can resume operations of data copying if interrupted, MySQL connection password is remembered across the MySQL Workbench session.
The GUI Tools bundle has been superseded by MySQL Workbench, and reached its End-of-Life with the beta releases of MySQL Workbench 5.2. However, the MySQL Support team continued to provide assistance for the bundle until June 30, 2010.
The MySQL GUI Tools Bundle is a cross-platform open source suite of desktop applications for the administration of MySQL database servers, and for building and manipulating the data within MySQL databases. It was developed by MySQL AB and later by Sun Microsystems and released under the GPL. Development on the GUI Tools bundle has stopped, and is now only preserved under the Download Archives of the MySQL site.
MySQL Workbench 5.0 and 5.1 are specialized visual database design tools for the MySQL database. While MySQL Workbench 5.0 was a MS Windows-only product, cross-platform support was added to MySQL Workbench 5.1 and later.
The MySQL server software itself and the client libraries use dual-licensing distribution. They are offered under GPL version 2, or a proprietary license.
Up until MySQL 5.7, triggers are limited to one per action / timing, meaning that at most one trigger can be defined to be executed after an INSERT operation, and one before INSERT on the same table. No triggers can be defined on views.
MySQL was created by a Swedish company, MySQL AB, founded by David Axmark, Allan Larsson and Michael "Monty" Widenius. Original development of MySQL by Widenius and Axmark began in 1994. The first version of MySQL appeared on 23 May 1995. It was initially created for personal usage from mSQL based on the low-level language ISAM, which the creators considered too slow and inflexible. They created a new SQL interface, while keeping the same API as mSQL. By keeping the API consistent with the mSQL system, many developers were able to use MySQL instead of the (proprietarily licensed) mSQL antecedent.
There are, however, limits to how far performance can scale on a single server ('scaling up'), so on larger scales, multi-server MySQL ('scaling out') deployments are required to provide improved performance and reliability. A typical high-end configuration can include a powerful master database which handles data write operations and is replicated to multiple slaves that handle all read operations. The master server continually pushes binlog events to connected slaves so in the event of failure a slave can be promoted to become the new master, minimizing downtime. Further improvements in performance can be achieved by caching the results from database queries in memory using memcached, or breaking down a database into smaller chunks called shards which can be spread across a number of distributed server clusters.
Oracle MySQL offers a high availability solution with a mix of tools including the MySQL router and the MySQL shell. They are based on Group Replication, open source tools.
XtraBackup is an open-source MySQL hot backup software program. Features include hot, non-locking backups for InnoDB storage, incremental backups, streaming, parallel-compressed backups, throttling based on the number of I/O operations per second, etc.
In addition to the standard expression, MySQL provides an function as an extension:
After MySQL was acquired by Sun, Monty joined the team working on Drizzle. which subsequently moved to Rackspace after the Oracle acquisition of Sun.
MySQL can also be run on cloud computing platforms such as Microsoft Azure, Amazon EC2, Oracle Cloud Infrastructure. Some common deployment models for MySQL on the cloud are:
Third-party proprietary and free graphical administration applications (or "front ends") are available that integrate with MySQL and enable users to work with database structure and data visually. Some well-known front ends are:
