The JavaScript Connector for MySQL you never heard of
Employee_Team +0 Vote Up -0Vote Down

It’s easier now than ever before to stand up a web server and connect it to a database using node.js and Express. Using node.js to get data out of a relational database used to require that users become well versed in SQL technology.

So the MySQL dev team started on a project to make it trivial (well, easy) to store and retrieve documents from MySQL and deliver them to node.js applications. Without using SQL. The result is  called mysql-js and I’d like to introduce it to you. You can download it today at  …

Achieving Read-After-Write Semantics With Galera
+0 Vote Up -0Vote Down

Some applications, particularly those written with a single-node database server in mind, attempt to immediately read a value they have just inserted into the database, without making those those operations part of a single transaction. A read/write splitting proxy or a connection pool combined with a load-balancer can direct each operation to a different database node.

Since Galera allows, for performance reasons, a very small amount of “slave lag”, the node that is processing the read may have not yet applied the write. It can return old data, causing an application that did not expect that to misbehave or produce an error.

JSON and the MySQL Argonauts
Employee +1 Vote Up -0Vote Down

The MySQL 5.7.7 JSON lab release has been getting a lot of attention. At a recent conference, I was cornered by a developer who wanted to jump in with both feet by running this release on his laptop on the flight home. However the developer was not sure how to begin.

1. Down load the MySQL JSON release from http://labs.mysql.com/. You will get the choice of a Linux binary or source code. Please grab the binary if you are using Linux and un-gzip/tar the download.

2. Shut down the current running version of MySQL. I was lucky in …

More Cores or Higher Clock Speed?
+0 Vote Up -0Vote Down

This is a little quiz (could be a discussion). I know what we tend to prefer (and why), but we’re interested in hearing additional and other opinions!

Given the way MySQL/MariaDB is architected, what would you prefer to see in a new server, more cores or higher clock speed? (presuming other factors such as CPU caches and memory access speed are identical).

For example, you might have a choice between

  • 2x 2.4GHz 6 core, or
  • 2x 3.0GHz 4 core

which option would you pick for a (dedicated) MySQL/MariaDB server, and why?

And, do you regard the “total speed” (N cores * GHz) as relevant in the decision process? If so, when and to what degree?

Combining work with MySQL and MongoDB using Python
+0 Vote Up -0Vote Down

Recently i have reviewed a simple web application, where problem was with moving “read” count of news from main table to another table in MySQL. The logic is separating counting “read”s for news from base table. The way you can accomplish this task, you can create a new “read” table in MySQL, then add necessary code to news admin panel for inserting id,read,date into this new “read” table, while adding new articles. But for test purposes, i decide to move this functionality to MongoDB. Overall task is -> Same data must be in MySQL, counting logic must be in MongoDB and data must be synced from MongoDB to MySQL. Any programming language will be …

Using Perl and MySQL to automatically respond to retweets on twitter
+0 Vote Up -0Vote Down

In an earlier post titled Using Perl to send tweets stored in a MySQL database to twitter, I showed you a way to use MySQL to store tweets, and then use Perl to automatically send your tweets to twitter.

In this post, we will look at automatically sending a “thank you” to people who retweet your tweets – and we will be using Perl and MySQL again.

Just like in the first post, you will need to register your application with twitter via …
