TaskBoard is a free and open source application to keep a track of the tasks that needs to be done. It requires minimal dependencies to work. Database is stored in SQLite which eliminates the requirement of MySQL or any other database server.
This blog discusses newly added options for Percona XtraBackup 2.4.8 and how they can impact your database backups.
To avoid issues with MySQL 5.7 skipping the redo log for DDL, Percona XtraBackup has implemented three new options (
xtrabackup --lock-ddl
,
xtrabackup --lock-ddl-timeout
,
xtrabackup --lock-ddl-per-table
) that can be used to place MDL locks on tables while they are copied.
So why we need those options? Let’s discuss the process used to get there.
Originally, we found problems while running DDLs: Percona XtraBackup produced corrupted backups as described in two reports:

In his comment to my announcement of the previous post, Shane Bester kindly suggested to consider pretty printing the information about user variables from gdb. I tried to do this tonight, after a long working day, while working with the same Percona server 5.7.x on CentOS 6.9, and found several interesting details to share even before getting to the pretty printing part (that I'd surely try to avoid doing with Python anyway, as I am lazy and not in a mood to use that programming language for a decade already). So, I decided to share them in a separate …

Security
MariaDB Connector/J 2.1 adds verification of SSL certificate name mismatch functionality. When using SSL, the driver will check the hostname against the server's identity as presented in the server's certificate (checking alternative names or certificate CN) to prevent man-in-the-middle attacks.

[Read more]In this tutorial, we will install MySQL with phpMyAdmin along with Apache web server with PHP 5.6. MySQL is a free and open source relational management system. It stores data in tabular format. It is the most popular way of storing the data into the database. phpMyAdmin is also a free and open source application used to administrate a MySQL server instance through a rich graphical user interface.
In my last post about big MySQL deployments, I am quickly mentioning that InnoDB compression is allowing dividing disk usage by about 4.3 on a 200+ TiB dataset. In this post, I will give more information about this specific use case of InnoDB table compression and I will share some statistics and learnings on this system and subject. Note that I am not covering InnoDB page compression which is
Historically, the MySQL binary log has gone through a few revisions resulting in different versions of how the log is formatted. The following shows the version of the binary log and the MySQL version in which it appears. As you can see, version 4 is the current version of the binary log found in the current releases of MySQL.…
Today is my last day in Asia (China and Taiwan), and between the sessions I had the time to code a small proof-of-concept for people that are asking how they could read their writes on all nodes and ensure the read consistency with their last write ?
The usual (and easier) answer to this particular question is to read on the same host you just wrote. But currently MySQL provides you all the elements to force a consistent read across all the nodes of a group.
Since MySQL 5.7.5, we introduced session_track_gtidsand in 5.7.6 we also introduced GTIDs context to the OK packet (session tracker) (WL#6128 and WL#6972). So we can use this implementation in …
