Dear MySQL users,

MySQL Connector/Python 8.0.13 is the third GA release version of the
MySQL Connector Python 8.0 series. This series adds support for Python
3.7. 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

Why does anyone need one billion tables?

Percona Live Europe Presents: Need for speed – Boosting Apache Cassandra’s performance using Netty

My talk is titled Need for speed: Boosting Apache Cassandra’s performance using Netty. Over the years that I have worked in the software industry, making code run fast has fascinated me. So, naturally when I first started contributing to Apache Cassandra, I started looking opportunities to improve its performance. My talk takes us through some interesting challenges within a distributed system like Apache Cassandra and various techniques to significantly improve its performance. Talking about performance is incredibly exciting because you can easily quantify and see the results. Making improvements to the database’s performance not only improves the user experience but also reflects positively on the organization’s bottom line. It also has the added …

ProxySQL 1.4.11, released by ProxySQL, is now available for download in the Percona Repository along with an updated version of Percona’s proxysql-admin tool.

ProxySQL is a high-performance proxy, currently for MySQL and its forks (like Percona Server for MySQL and MariaDB). It acts as an intermediary for client requests seeking resources from the database. René Cannaò created ProxySQL for DBAs as a means of solving complex replication topology issues.

Picking a Deployment Method: Staging versus INI

Tungsten Clustering is an extraordinarily flexible tool, with options at every layer of operation.

In this blog post, we will describe and discuss the two different methods for installing, updating and upgrading Tungsten Clustering software.

When first designing a deployment, the question of installation methodology is answered by inspecting the environment and reviewing the customer’s specific needs.

Staging Deployment Methodology

All for One and One for All

Staging deployments were the original method of installing Tungsten Clustering, and relied upon command-line tools to configure and install all cluster nodes at once from a central location called the staging server.

This staging server (which could be one of the cluster nodes) requires SSH access to all …

Percona Live Europe Presents: MariaDB System-Versioned Tables

System-versioned tables, or temporal tables, are a typical feature of proprietary database management systems like DB2, Oracle and SQL Server. They also appeared at some point in PostgreSQL, but only as an extension; and also in CockroachDB, but in a somewhat limited fashion.

The MariaDB® implementation is the first appearance of temporal tables in the MySQL ecosystem, and the most complete implementation in the open source world.

My presentation will be useful for analysts, and some managers, who will definitely benefit from learning how to use temporal tables. Statistics about how data evolves over time is an important part of their job. This feature will allow them to query data as it was at a certain point in time. Or to query how data changed over a period, including rows that were …
