Balada Para Un Loco – A Review of the MySQL, NoSQL, and Cloud Conference
+1 Vote Up -0Vote Down

… Ya se que estás piantao, piantao, piantao…

For my lastest blog, a review of the MySQL, NoSQL and Cloud Conference, I’ll continue to use the tango metaphor. Balada para un loco (ballad for a crazy one) is a Piazzola classic and explains what I think of Santiago Lertora from Binlogic for single handedly putting together this event; he had to be piantao (slang for ‘crazy’) to pursue his vision to kick start the Open Source database community in South America into becoming as active as it is in the US and Europe. He was able to gather some renowned speakers such as our own Martin Farach-Colton, Sheeri Cabral from Mozilla, Max Mether and Massimo Brignoli from SkySQL, Colin Charles from Monty Program, Alejandro Kojima

NoSQL Java API for MySQL Cluster: Questions & Answers
Employee_Team +3 Vote Up -0Vote Down

The MySQL Cluster engineering team recently ran a live webinar, available now on-demand (http://www.mysql.com/news-and-events/on-demand-webinars/display-od-716.html) demonstrating the ClusterJ and ClusterJPA NoSQL APIs for MySQL Cluster (http://www.mysql.com/products/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

The catch-22 of read/write splitting
+2 Vote Up -0Vote Down
In my previous post I covered the shard-disk paradigm's pros and cons, but the conclusion that is that it cannot really qualify as a scale-out solution, when it comes to massive OLTP, big-data, big-sessions-count and mixture of reads and writes.

Read/Write splitting is achieved when numerous replicated database servers are used for reads. This way the system can scale to cope with increase in concurrent load. This solution qualifies as a scale-out solution as it allow expansion beyond the boundaries of one DB, DB machines are shared-nothing, can be added as a slave to the replication "group" when required.

The Sound and the NoSQL Fury
+0 Vote Up -0Vote Down

The signal-to-noise ratio in the NoSQL world has made it hard to figure out what’s going on, or even who has something new. For all the talk of performance in the NoSQL world, much of the most exciting part of what’s new is really not about performance at all.

Take for example, MongoDB, which has a really great data model and MapReduce has a very handy scripting language. These are genuine and probably long-lasting contributions. Their innovation is all about finding a new language to use for interacting with data. They are about NoSQL.

The confusion comes, for me, when we get to the performance side of the equation. I explore this in detail in an article I did for Datanami recently – http://www.datanami.com/datanami/2012-05-22/the_sound_and_the_nosql_fury.html.

451 Research delivers market sizing estimates for NoSQL, NewSQL and MySQL ecosystem
+0 Vote Up -0Vote Down

NoSQL and NewSQL database technologies pose a long-term competitive threat to MySQL’s position as the default database for Web applications, according to a new report published by 451 Research.

The report, MySQL vs. NoSQL and NewSQL: 2011-2015, examines the competitive dynamic between MySQL and the emerging NoSQL non-relational, and NewSQL relational database technologies.

It concludes that while the current impact of NoSQL and NewSQL database technologies on MySQL is minimal, they pose a long-term competitive threat due to their adoption for new development projects. The report includes market sizing and growth estimates, with the key findings as follows:

• NoSQL software vendors generated revenue* of $20m in 2011. NoSQL software revenue is expected to rapidly grow at a CAGR of 82% to reach $215m by

Simple and efficient MongoDB Backup using script
+0 Vote Up -1Vote Down

MongoDB Backup types and strategies are neatly explained in its documentation, which you can check here. In case you are not familiar with MongoDB backup types and strategies, please have a look at its documentation.

What I am describing here is a simple script which we are using since months to take MongoDB backup and transfer it over to our Backup server. Here are few things its doing:

  • As we have multiple MongoDB Replica Sets, the script identify current replica set and check whether current server is Master or Slave, exit if its Master. We take backup only from Slave host.
  • Take Backup using mongodump command.
  • Upon successful completion of dump, transfer that to our Backup server. Ensure that ssh key based authentication is setup between both servers to implement seamless and

Designing a HTTP JSON database api
+0 Vote Up -0Vote Down

A few weeks ago I blogged about the HTTP JSON api in Drizzle. (See also a small demo app using it.) In this post I want to elaborate a little on the design decisions taken. (One reason to do this is to provide a foundation for future work, especially in the form of a GSoC project.)

Looking around: MongoDB, CouchDB, Metabase
