MySQL 8: Drop Several Stored Events, Procedures, or Functions

Tweet

Maybe the biggest new feature in MySQL 8 is the new transaction data dictionary that improves the consistency of schema objects among other things. To further protect the data in the data dictionary, the data dictionary tables are hidden and their content only exposed through the Information Schema. (One exception is when you use the debug binary, then it is possible to get direct access to the data dictionary tables. This is not recommended at all on production systems!)

A side effect of the data dictionary tables being hidden is that those that have had a habit of manipulating the tables directly in MySQL 5.7 and earlier (I will not recommend doing that) will no longer be able to do so. Examples of manipulating the tables include …

MySQL X DevAPI Connection Pool with Connector/Python

Tweet

If you have an application that need to use multiple connections to the MySQL database for short periods of times, it can be a good to use a connection pool to avoid creating a new connection and going through the whole authentication process every time a connection is needed. For the Python Database API (PEP249), MySQL Connector/Python has had support for connection pools for a long time. With the release of MySQL 8.0.13, the new X DevAPI also has support for connection pools.

This blog will first cover the background of the X DevAPI connection pool feature in MySQL Connector/Python. Then provide an …

First of all, thanks to everyone who attended my sessions at the recent Oracle OpenWorld and Code One in San Francisco. It was a great privilege to be allowed to make a number of presentations.

All of the workbooks and scripts from the hands-on labs (HOL) and the slides from the talks have been made available at OpenWorld’s and Code One’s session catalogues. You can download the files by using the OpenWorld catalog searching for my name or the session number (see below). Click on the download icon for each of the presentations you are interested in.

NoSQL/X DevAPI Tutorial with MySQL Connector/Python 8.0

Tweet

The MySQL Document Store became general available (GA) with MySQL 8. One of the nice features of the MySQL Document Store is the X DevAPI that allows you to query the data from a multitude of programming languages using the same API (but while retaining the conventions of the language). The programming languages with support for the X DevAPI includes JavaScript (Node.js), PHP, Java, DotNet, and C++.

I will be using MySQL Connector/Python 8.0.12 for the example in this blog. The example is executed on Microsoft Windows with Python 3.6 installed, but it has also been tested on Oracle Linux 7 with Python 2.7. I do assume that MySQL Connector/Python has been installed. If that is not the case, you can read how to do it in the …

A small dive into the MySQL 8.0 X-DevAPI

Introduction

What is the X-DevApi? From insidemysql.com there is a definition of the X-DevAPI and its features in the following paragraphs:

The X DevAPI is the common client-side API used by all connectors to abstract the details of the X Protocol. It specifies the common set of CRUD-style functions/methods used by all the official connectors to work with both document store collections and relational tables, a common expression language to establish query properties such as criteria, projections, aliases, and a standard set of additional database management features for handling things like transactions, indexes, etc.

The fact that most of these features share the same format and API between connectors, makes the X DevAPI a perfect fit for modern polyglot development environments such as microservices, and the fact that they are based on a …
