Do you have registered users who can’t connect to the MySQL server? Strangers modifying data to which they shouldn’t have access?

MySQL supports a rich set of user privilege options and allows you to fine tune access to every object in the server. The latest versions support authentication plugins that help to create more access patterns.

However, finding errors in …

In this blog post, we’ll look at a workaround for MySQL bug 72804.

Recently I worked on a ticket where a customer performed a point-in-time recovery PITR using a large set of binary logs. Normally we handle this by applying the last backup, then re-applying all binary logs created since the last backup. In the middle of the procedure, their new server crashed. We identified the binary log position and tried to restart the PITR from there. However, using the option

--start-position

, the restore failed with the error “The BINLOG statement of type Table_map was not preceded by a format description BINLOG statement.” This is a known bug and is reported as MySQL …

In this blog we’ll look at the results from Percona’s blog poll on what programming languages you’re using for backend development.

Late last year we started a poll on what backend programming languages are being used by the open source community. The three components of the backend – server, application, and database – are what makes a website or application work. Below are the results of Percona’s poll on backend programming languages in use by the community:

Note: There is a poll embedded within this post, please visit the site to participate in this post's poll.

One of the best-known and earliest web service stacks is the LAMP stack, which spelled out refers to Linux, Apache, MySQL and PHP/Perl/Python. We can see that this early model is still popular when it comes to the backend.

In this blog we are going to explore about innodb tablespace encryption technique, which will be useful for securing data.

In MySQL 5.7, a new feature “Innodb Tablespace Encryption“has been added to protect the data at rest. This is a most awaited feature in security. This encryption supports all file per table tablespaces and it will not  support shared tablespace. This encryption technique works on the basis of rotating  key files. There are two types of keyring plugins available for the key management and they are given below

• keyring_file plugin – Available in all MySQL versions.

• keyring_okv plugin – Available in MySQL Enterprise Edition.

Architecture:

Innodb tablespace encryption uses two tier encryption architecture, in which it has master encryption key …

FOSDEM 2017 is over, I brought back home the flu…. but hopefully not only !

Indeed this 2017 edition was very rewarding. We started our FOSDEM with a “fringe” : pre-FOSDEM MySQL Day where we highlighted MySQL 8.0 new features and hosted some talks from MySQL friends.

This first edition of the pre-FOSDEM MySQL Day was a great success. We had up to 70 attendees! I would like to thanks all the speakers: Morgan Tocker, Bernt Marius Johnsen, Øystein Grøvlen, Kenny Gryp, Jean-François Gagné, Dag H. Wanvik, …
