MySQL Document Store Video Series

I am starting a series of videos on the MySQL Document Store. The Document Store allows those who do not know Structured Query Language (SQL) to use a database without having to know the basics of relational databases, set theory, or data normalization. The goal is to have sort 2-3 minute episodes on the various facets of the Document Store including the basics, using various programming languages (Node.JS, PHP, Python), and materializing free form schemaless, NoSQL data into columns for use with SQL.

The first Episode, Introduction, can be found here.

Please provide feedback and let me know if there are subjects you would want covered in the near future.

A Little Trick Upgrading to MySQL 5.7

In this blog post, I’ll look at a trick we use at Percona when upgrading to MySQL 5.7.

I’ll be covering this subject (and others) in my webinar Learning MySQL 5.7 on Wednesday, July 19, 2017.

We’ve been doing upgrades for quite a while here are Percona, and we try to optimize, standardize and improve this process to save time. When upgrading to MySQL 5.7, more often than not you need to run REPAIR or ALTER via mysql_upgrade to a number of MySQL tables. Sometimes a few hundred, sometimes hundreds of thousands.

One way to cut some time from testing or executing mysql_upgrade is to combine it with mysqlcheck. This identifies tables that need to be rebuilt or repaired. The first …

Setting Up Percona PAM with Active Directory for External Authentication

In this blog post, we’ll look at how to set up Percona PAM with Active Directory for external authentication.

In my previous article on Percona PAM, I demonstrated how to use Samba as a domain, and how easy it is to create domain users and groups via the samba-tool. Then we configured nss-pam-ldapd and nscd to enumerate user and group information via LDAP calls, and authenticate users from this source.

This time around, I will demonstrate two other ways of using Active Directory for external authentication by joining the domain via SSSD or Winbind. System Security Services Daemon (SSSD) allows you to configure …

Gh-ost benchmark against pt-online-schema-change performance

In this blog post, I will run a gh-ost benchmark against the performance of pt-online-schema-change.

When gh-ost came out, I was very excited. As MySQL ROW replication became commonplace, you could use it to track changes instead of triggers. This practice is cleaner and safer compared to Percona Toolkit’s pt-online-schema-change. Since gh-ost doesn’t need triggers, I assumed it would generate lower overhead and work faster. I frequently called it “pt-online-schema-change on steroids” in my talks. …
