Use MySQL to store data from Amazon’s API via Perl scripts

I really like Amazon.com and I have been a Prime member for several years. Along with millions of different items for sale, Amazon has an affiliate program, where you can earn money advertising products on your web site. When a visitor to your site clicks on a link and orders a product from Amazon, you earn a small commission on the total sale. As an affiliate, you have access to Amazon’s Product Advertising API for obtaining product information. But, you can use this information for many other purposes.

The Amazon API is like most other API’s, and their API web site provides you with code examples and explains how it all works. I am going to show you how a Perl program which you can use to access the API data and store it in a …

The Client Library, Part 2: The Version Number

The client library — libmysqlclient — is part of the same source code repository as the server. It comes both as a dynamic link library (.so), also called a shared library, and as a static link library (.a). During the 5.7 development cycle, we’ve made several improvements to the library, which has resulted in a bump from ABI version 18 to version 20.…

C Library Visibility

I was surprised by the recent announcement that MySQL are going to start to conceal the hidden function calls in their C connector. Surprised because although this is great news I had expected them to do this years ago. Working for HP's Advanced Technology Group I realise I take such things for granted. For this blog post I'm going to talk about why it is important and how to do it.

So, when you create a dynamic library in C the default thing that happens is every function call in that library effectively becomes a potential API call. Whether you document every single function or not to make it official API is up to you but I suspect in 99.99% of cases there are private functions you don't want users to mess with. Additionally holding the symbol information for every function so that you can link your application to it takes a …

Experiences with the McAfee MySQL Audit Plugin

I recently had to do some customer work involving the McAfee MySQL Audit Plugin and would like to share my experience in this post.

Auditing user activity in MySQL  has traditionally been challenging. Most data can be obtained from the slow or general log, but this involves a lot of data you don’t need too, and isn’t flexible at all. The specific problem of logging failed connection attempts has been discussed on a previous post in our blog.

Starting with 5.1, the new plugin API gives us more flexibility by allowing users to extend the server’s functionality with their own code, and this is what the McAffee plugin does.

Installation and …

NoSQL Memcached API for MySQL: Latest Updates

With data volumes exploding, it is vital to be able to ingest and query data at high speed. For this reason, MySQL has implemented NoSQL interfaces directly to the InnoDB and MySQL Cluster (NDB) storage engines, which bypass the SQL layer completely. Without SQL parsing and optimization, Key-Value data can be written directly to MySQL tables up to 9x faster, while maintaining ACID guarantees.

In addition, users can continue to run complex queries with SQL across the same data set, providing real-time analytics to the business or anonymizing sensitive data before loading to big data platforms such as Hadoop, while still maintaining all of the advantages of their existing relational database infrastructure.

This and more is discussed in the latest Guide to MySQL and …

MySQL Syslog Audit Plugin

This post shows the construction process of the Syslog Audit plugin that was presented at MySQL Connect 2012. It is based on an environment that has the appropriate development tools enabled including gcc,g++ and cmake. It also assumes you have downloaded the MySQL source code (5.5.16 or higher) and have compiled and installed the system into the /usr/local/mysql directory ready for use. 

The information provided below is designed to show the different components that make up a plugin, and specifically an audit type plugin, and how it comes together to be used within the MySQL service. The MySQL Reference Manual contains information regarding the plugin API and how it can be used, so please refer there for more detailed information. The code in this post is designed to …

NoSQL Java API for MySQL Cluster: Questions & Answers

The MySQL Cluster engineering team recently ran a live webinar, available now on-demand demonstrating the ClusterJ and ClusterJPA NoSQL APIs for MySQL Cluster, and how these can be used in building real-time, high scale Java-based services that require continuous availability.

Attendees asked a number of great questions during the webinar, and I thought it would be useful to share those here, so others are also able to learn more about the Java NoSQL APIs.

First, a little bit about why we developed these APIs and why they are interesting to Java developers.

ClusterJ and Cluster JPA

ClusterJ is a Java interface to MySQL Cluster that provides either a static or dynamic domain object model, similar to the data model used by JDO, …
