MariaDB came into being the day that Oracle announced the purchase of Sun in 2010.  In order to keep it free under the GNU GPL, Michael Widenius forked MySQL and took several MySQL developers with him in the process.  Since then, MariaDB has been a drop-in replacement for MySQL, albeit with more features and better performance.

In the Improve MariaDB Performance using Query Profiling blog, we learned some useful techniques for tracking and analyzing slow queries using a couple of MariaDB server’s built-in tools: the Slow Query Log and the Performance Schema.  

The Slow Query Log records queries that are deemed to be slow and potentially problematic, that is, queries that take longer than the long_query_time global system variable value to run.

The Performance Schema is a storage engine …

Query profiling is a useful technique for analyzing the overall performance of a database. Considering that a single mid-to-large sized application can execute numerous queries each and every second, query profiling is an important part of database tuning, both as a proactive measure and in diagnosing problems.  In fact, it can become difficult to determine the exact sources and causes of bottlenecks and sluggish performance without employing some sort of query profiling techniques. This blog will present a few useful query profiling techniques that exploit MariaDB server’s own built-in tools: the Slow Query Log and the Performance Schema.

MariaDB vs. MySQL

Needless to say, the techniques that we’ll be covering here today are likely to be equally applicable to MySQL, due to the close relationship between the two products.

Changes as compared to Monyog MySQL Monitor v8.4.1 include:

This release fixes a few minor bugs only and implements a number of user requests.

Features:

• Monyog can now analyze MariaDB and MySQL enterprise Audit log.
• Added support for LDAP with StartTLS and SSL.
• The default path for MONyog.log can be changed using the parameter “MONyogLogPath” from the MONyog.ini file.

Bug Fixes:

• Monyog logged bogus SQLite errors on fresh installation.
• Monyog displayed console error if LDAP group name contained inverted comma.
• Changed alert condition for “Seconds behind master” monitor to consider “NULL” as an alertable condition. It considered the value “NULL” stable condition earlier.
• On upgrading, Monyog filled the mail alert field for sniffer with the bogus email id “admin@mydomain.com”.
• On selecting a …

Although there is no official software release for MySQL 8.0 as of yet, most insiders believe that it’s likely to arrive sometime in 2018.  In the meantime, Oracle has officially announced a tantalizing list of over two hundred new features!   We recently covered Replication Performance Enhancements.  Today’s blog will cover some of the other exciting enhancements we can expect when the production release of MySQL 8 hits the market.

New Database Roles

A role is a named collection of privileges that define what a user can and cannot do within a database. Roles play a vital part of database security by limiting who can connect to the server, access the database, or even access individual database objects and data.

Although prior to version 8, MySQL did provide a set of Privileges and Administrative Roles, the up-coming release will also support a set of flexible and properly …

Although it feels like it was only yesterday that Oracle released version 5.7 of their acclaimed MySQL Community Server, version 8 is already available as a development milestone release (DMR). No, you didn’t sleep through a bunch of releases; MySQL is jumping several versions in its numbering due to 6.0 being dropped and 7.0 being reserved for the clustering version of MySQL. This new version boasts numerous changes (and bug fixes), one of the most exciting of which are replication enhancements. This blog will provide an overview of the new replication enhancements, including new replication timestamps, additional information reported by performance schema tables, and how replication delay has been reduced by updating the relationship between replication threads to make them more efficient.

New Replication Timestamps

The most common task when managing a …

With this Monyog release, we will provide monitoring capabilities for RDS/Aurora OS metrics along with an emphasis on the User Experience in several respects including a number of GUI design details. Additionally, the release adds a number of bug fixes and implements a number of user requests.

Changes as compared to Monyog MySQL Monitor 8.0.4 include:

Features:

• It is now possible to get OS metrics from Amazon RDS/Aurora (but not Azure, where interface for same is disabled).
• Added an option to generate a token in Monyog to be used with the MONyog API as an alternative to Monyog user and password.
• Added an option to define a “seconds_behind_master” setting in Replication page determining if the slave should be considered in sync or not. On some environments, slave will rarely be fully in sync and in such cases, the alerting was not really useful before. …
