Our 2013 Database survey is now live
+0 Vote Up -0Vote Down

451 Research’s 2013 Database survey is now live at http://bit.ly/451db13 investigating the current use of database technologies, including MySQL, NoSQL and NewSQL, as well as traditional relation and non-relational databases.

The aim of this survey is to identify trends in database usage, as well as changing attitudes to MySQL following its acquisition by Oracle, and the competitive dynamic between MySQL and other databases, including NoSQL and NewSQL technologies.

There are just 15 questions to answer, spread over five pages, and the entire survey should take less than ten minutes to complete.

All individual responses are of course

Well, it’s that time of the year again for top ten lists. There have been many versions showing up on the web the last few days, including Time Magazine’s “Top 10 Everything of 2012″ list, with 55 wide ranging lists!

Last year we started using Google Analytics to see what content for blogs was most popular on Tokutek.com and generated a 2011 top ten list, ending up with a few surprises.  This year saw spikes in some interesting areas as well, including flash performance, NASA and Big Data, and MongoDB.

Without further adieu, here is the top ten list for 2012:

2012, the Best Year for MySQL (...so far, but more to come)
+9 Vote Up -3Vote Down
It's the end of the year and, before the world ends ;-) , I feel the pressure to follow up on last year's article "2011, a great year for MySQL in Review". I'll adopt a similar format and mention things in context, covering products, marketing, momentum, etc. at a high level. I may have missed something and I hope my colleagues will contribute to the list.

I really do think it's been the best year for MySQL so far... well, at least since when I signed my contract with MySQL AB at the end of 2007. We're just at the beginning of our journey and I wish to the MySQL family, to our community and ecosystem an even better 2013!

NoSQL Memcached API for MySQL: Latest Updates
Employee_Team +4 Vote Up -0Vote Down

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 (http://www.mysql.com/products/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 NoSQL

“Some people even think that “Hadoop” and “Big Data” are synonymous (though this is an over-characterization). Unfortunately, Hadoop was designed based on a paper by Google in 2004 which was focused on use cases involving unstructured data (e.g. extracting words and phrases from Webpages in order to create Google’s Web index).

MySQL and Hadoop Integration - Unlocking New Insight
Employee_Team +4 Vote Up -0Vote Down

“Big Data” offers the potential for organizations to revolutionize their operations. With the volume of business data doubling every 1.2 years, analysts and business users are discovering very real benefits when integrating and analyzing data from multiple sources, enabling deeper insight into their customers, partners, and business processes.

As the world’s most popular open source database, and the most deployed database in the web and cloud, MySQL is a key component of many big data platforms, with Hadoop vendors estimating 80% of deployments are integrated with MySQL.

The new Guide to MySQL and Hadoop (http://www.mysql.com/why-mysql/white-papers/mysql_wp_hadoop.php) presents the tools enabling integration between the two data platforms, supporting the data lifecycle from

Election 2012: Twitter Breaks Records with MySQL
Employee_Team +8 Vote Up -0Vote Down
Twitter VP of Infrastructure Operations Engineering Mazen Rawashdeh shared news and numbers yesterday on his blog:

"Last night, the world tuned in to Twitter to share the election results as U.S. voters chose a president and settled many other campaigns. Throughout the day, people sent more than 31 million election-related Tweets (which contained certain key terms and relevant hashtags). And as results rolled in, we tracked the surge in election-related Tweets at 327,452 Tweets per minute (TPM). These numbers reflect the largest election-related Twitter conversation during our 6 years of existence, though they don’t capture the total volume of all Tweets yesterday."

Open World 2012
+0 Vote Up -0Vote Down

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

MySQL Oracle Connect 2012: Day One
+2 Vote Up -0Vote Down

I attend five sessions today, and I think that some of them were very interesting, like the one on the Optimizer insight. It was quite informative and accurate.

Another one, done by the MySQL Cluster (NDB) group on the installer and new Javascript API interface, left me a little bit…foggy. Why? Because in my mind, one of the most important things to accomplish in NDB is the correct dimensioning of the memory, buffers, possible operation, attributes, and so on. All these things should come from the schema definition review and from the application analysis.

Now given the review analysis of the schema is still not present in the installer, I think that we missed a very important piece of information. When I raised the issue, Bernd mentioned that they were thinking of integrating that as well. It’s a good move, and I hope to see it soon. About the

MySQL Oracle Connect 2012 Keynotes
+1 Vote Up -0Vote Down

I’m excited to be here not only to catch up with old friends and ex-colleagues, but also to witness what seems to be the start of a very significant conference from MySQL.

I really enjoyed the introductions done by Edward Screven and Thomas Ulin. Edward highlighted the fact that MySQL is increasing its presence in the market and in the community. This could be thanks to the unbelievable effort done by Oracle in keeping its production cycle on target. Thomas stressed that point and gave a great description of it. He demonstrated Oracle’s main focus points, which are mainly on InnoDB, with implementation and enhancement of the internal contentions, then on Optimizer improvements and NoSQL integration.

Replication remains a pending issue from my side because if we have the global transaction ID, we still suffer from delay in replication given that parallel

Tutorial: Getting Started with the NoSQL JavaScript / Node.js API for MySQL Cluster
Employee_Team +2 Vote Up -0Vote Down

Tutorial authored by Craig Russell and JD Duncan 

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 implementation is designed to plug and play with Node.js, the actual

Looking for MongoDB users to test Fractal Tree Indexing

In my three previous blogs I wrote about our implementation of Fractal Tree Indexes on MongoDB, showing a 10x insertion performance increase, a 268x query performance increase, and a comparison of covered indexes and clustered indexes. The benchmarks show the difference that rich and efficient indexing can make to your MongoDB workload.

It’s one thing for us to benchmark MongoDB + TokuDB and another to measure real world performance. If you are looking for a way to improve the performance or

268x Query Performance Increase for MongoDB with Fractal Tree Indexes, SAY WHAT?
+1 Vote Up -0Vote Down

Last week I wrote about our 10x insertion performance increase with MongoDB. We’ve continued our experimental integration of Fractal Tree® Indexes into MongoDB, adding support for clustered indexes.  A clustered index stores all non-index fields as the “value” portion of the index, as opposed to a standard MongoDB index that stores a pointer to the document data.  The benefit is that indexed lookups can immediately return any requested values instead of needing to do an additional lookup (and potential disk IOs) for the requested fields.

To create a clustered index you just need to add

10x Insertion Performance Increase for MongoDB with Fractal Tree Indexes
+3 Vote Up -0Vote Down

The challenge of handling massive data processing workloads has spawned many new innovations and techniques in the database world, from indexing innovations like our Fractal Tree® technology to a myriad of “NoSQL” solutions (here is our Chief Scientist’s perspective). Among the most popular and widely adopted NoSQL solutions is MongoDB and we became curious if our Fractal Tree indexing could offer some advantage when combined with it. The answer seems to be a strong “yes”.

Earlier in the summer we kicked off a small side project and here’s what we did: we implemented a “version 2” IndexInterface as a Fractal Tree index and ran some benchmarks. Note that our integration only affects MongoDB’s secondary indexes;

MySQL as a Key Value Store (KVS) - Why, some background and some more tests

You might have seen my attempts at testing MySQL as a Key Value Store (KVS) (here and here), i.e. used like MongoDB, and I have had some comments to those. Above all, many wanted to know the details of my test environment. To be honest, this started off as a very simple thing, but it turned out a bigger than I thought, so I guess its reasonable to give some background. I apologize for not giving you this background before, but as I said, my initial intention was to just run bog standard MongoDB versus MySQL and see what happened.  [Read more...]
Exploring Configuration Management with Ansible
+0 Vote Up -0Vote Down

 

What is Ansible?

Ansible is a configuration management and deployment system, like Puppet, Capistrano, Fabric, and Chef. Its aim is to be radically simple and let you use your existing scripts to help with cluster configuration and software deployment whenever possible. Here are the ways that Ansible differentiates itself.

Simplicity

Ansible does not include a client/server architecture with pull-based clients (although in more recent versions, it does include pull-based configuration and deployment). Rather, it uses pre-existing network infrastructure: SSH. Every company has SSH installed on their cluster servers, and Ansible simply rides on top of this infrastructure to get the code and configuration out to the nodes.

Developer-Driven Databases
+0 Vote Up -0Vote Down

Even though I have come late to the party of professional development, relatively speaking, I am acutely aware of the conflict that seems to pervade the developer-DBA relationship. This is what I gather about why this is: DBAs used to be paid better that developers, and often this was because they were able to reduce the overall license and hardware costs of large database installations. Both the size and proprietary nature of databases made them incredibly expensive, so paying an individual gobs of money to make sure they ran efficiently and that the data was preserved was worth it.

Several trends have changed the playing field. The first is the arrival of small, commodity server hardware that makes mainframes or large servers unnecessary, and thus the cost is pushed down dramatically for most
