On Thursday 12th September I’ll be co-presenting a free webinar on how MySQL Cluster delivers the key benefits of NoSQL Data Stores without having to give up the features that people rely on from relational databases (consistency, SQL etc.). There will be particular focus on how to use the new node.js JavaScript API which was recently released as part of MySQL Cluster 7.3.  As usual the webinar is free but you should …

We’re very pleased to announce that MySQL Cluster 7.3 has gone GA; for a full run-down of the new features and enhancements, take a look at the "MySQL Cluster 7.3 New Features for Internet-Scale Performance with Carrier-Grade Availability" white paper but this post will focus on just one of the features – the MySQL Cluster JavaScript Driver for Node.js. The post will step you through setting everything up so that you can get your first Node.js code reading and writing from MySQL Cluster.

Background

MySQL Cluster is a distributed, shared nothing database that provides linear scalability, 99.999% availability and high read/write throughput with low latency. SQL is …

Today social media applications plays an important role in our day-to-day activities as a result of the Web 2.0 revolution that took place in the Internet. It has revolutionized the lifestyle of almost all the individuals and business entities, for the majority of them spending at least few minutes with it has become an integral […]

The MySQL Cluster team are working on a new NoSQL JavaScript connector for MySQL. The objectives are simplicity and high performance for JavaScript users:

- allows end-to-end JavaScript development, from the browser to the server and now to the world's most popular open source database

- native "NoSQL" access to the storage layer without going first through SQL transformations and parsing.

Node.js is a complete web platform built around JavaScript designed to deliver millions of client connections on commodity hardware. With the MySQL NoSQL Connector for JavaScript, Node.js users can easily add data access and persistence to their web, cloud, social and mobile applications.

While the initial …

Just a quick note to say that the site has been updated to a new theme which is based on the super awesome Twitter Bootstrap UI framework. To make life easier, since this site is also using WordPress at the core, I’ve made use of the WordPress Bootstrap plugin which allows for very simple integration. However, that wasn’t enough because the Bootstrap plugin comes with rather basic and boring generic styles; so I added the plugin for Google Font support and then modified the CSS accordingly.

You will also notice that the site is undergoing some reorganization of categories and content tags. This should help clean up search results as well as general information sorting. I’ve removed the sidebar widget for category listings in favor …

Unfortunately jQuery doesn’t come with default form validation to check for ip-addresses or subnet masking. So without a long winded explanation here’s the code. Just include this as a separate JS file like the rest of your page’s JS.

// 'ipv4': IPv4 Address Validator
$.validator.addMethod('ipv4', function(value) {
    var ipv4 = /^[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}$/;    
    return value.match(ipv4);
}, 'Invalid IPv4 address');

// 'netmask': IPv4 Netmask Validator
$.validator.addMethod('netmask', function(value) {
    var mask = /^[1-2]{1}[2,4,5,9]{1}[0,2,4,5,8]{1}\.
[0-2]{1}[0,2,4,5,9]{1}[0,2,4,5,8]{1}\.
[0-2]{1}[0,2,4,5,9]{1}[0,2,4,5,8]{1}\.
[0-9]{1,3}$/;    
    return value.match(mask);
}, 'Invalid IPv4 netmask');

You can use it like this.

$("#myform_here").validate({
    rules:{
        ipaddress:{
            required:true,
            ipv4:true
        },
        netmask:{ …

Full table scan vs full index scan performance

Author: Stephane Combaudon.

Using full index scans are not always faster than a full table scan. Stephane explores the situations in which a sequential read through of a full table performs better than using randomly-read full index.

Big Data …

In prior years a daily update from Open World was possible, but this year my schedule was too full to support it. This is my compendium of thoughts about MySQL Connect, JavaOne, and Open World 2012.

MySQL Connect was great – good sessions re-enforcing the positive investments Oracle is making in the product. I’ll leave to others to qualify changes in what elements of technology are opened or closed along the road to a better MySQL. The announcement of Connector/Python 1.0 GA on Saturday was great news and as a community we owe a lot to Greet Vanderkelen.

NoSQL is a hot topic along with using JSON objects and it was interesting hearing of some unequal testing paradigms to position non-Oracle solutions to be “better” …
