MariaDB non-blocking client API and node.js

Last Summer I implemented a non-blocking client API in MariaDB, and it was included in the MariaDB 5.5 release. But somehow I never got around to announcing it.

However, that did not prevent Brian White from noticing it, and using it to implement a new mysql binding for node.js called mariasql.

Now, node.js is a single-threaded, event-driven framework for web application sever development. In such frameworks, all I/O is done non-blocking or asynchronously, as are all other actions that may need to wait for external events. There is a single event loop which uses a poll() or similar system call to wait for any pending I/O or other event to complete, and then dispatches the appropriate event handler(s). …

Making it easier to follow and participate in MariaDB development

In June, I told about the consolidation of the MariaDB project tools. The final piece of this consolidation, to report bugs in the MariaDB project tracking tool called JIRA has now been finalized.

Bug reporting stays open! JIRA is open to anyone. The bug reports are publicly available, even without logging in and as a bonus it will be easier to follow what is going on in the project since you don’t have to jump between several tools to get the complete picture.

All bugs that existed in Launchpad have been migrated to JIRA. To find a bug that was originally reported on Launchpad use the following approaches:

  • If you happen to have the original bug id you can search for the bug by typing lp:bugid into the search field in the upper right corner of JIRA.

Announcing the Cassandra Storage Engine

We’re pleased to announce the first preview version of the Cassandra Storage Engine!

The Cassandra Storage Engine (SE) allows access to Cassandra databases from MariaDB/MySQL, and to provide data integration between the SQL and NoSQL worlds.

Have you ever needed to

  • grab some of Cassandra’s data from your web frontend, or SQL query?
  • insert a few records into Cassandra from some part of your app?

With Cassandra SE, this is easily possible. Cassandra SE makes Cassandra’s column families appear as MariaDB/MySQL tables that you can insert to, update, and select from. …

The Explain Analyzer and HeidiSQL

A few months ago we announced the EXPLAIN Analyzer, a simple tool to help you understand how MariaDB / MySQL was running queries. For users of HeidiSQL this is now even easier. As discussed in their news post you can now send a query to the EXPLAIN analyzer with a single click.

We hope this helps both new and experienced users better understand the queries they run.

More information about the EXPLAIN Analyzer and the simple API client authors can use to add support to their apps is available in the AskMonty Knowledgebase:
