Dear MySQL users,

MySQL Connector/Python 8.0.4 dmr is the fifth development release of the
MySQL Connector Python 8.0 series. This series adds support for the new X
DevAPI. The X DevAPI enables application developers to write code that
combines the strengths of the relational and document models using a
modern, NoSQL-like syntax that does not assume previous experience
writing traditional SQL.

To learn more about how to write applications using the X DevAPI, see
http://dev.mysql.com/doc/x-devapi-userguide/en/.

For more information about how the X DevAPI is implemented in
MySQL Connector/Python, and its usage, see

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.

MySQL 5.6 introduced  the fractional second precision for temporal data types – TIME, DATETIME, and TIMESTAMP,  with up to microseconds (6 digits) precision. Along with providing fractional second precision, the new implementation for temporals is disk efficient.

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 …
