MySQL meets NoSQL with JSON UDF
I recently got back from FOSDEM, in Brussels, Belgium. While I was there I got to see a great talk by Sveta Smirnova, about her MySQL 5.7 Labs release JSON UDF functions. It is important to note that while the UDF come in a 5.7 release it is absolutely possible to compile and use the UDF with earlier versions of MySQL because the UDF interface has not changed for a long time. However, the UDF should still be considered alpha/preview level of quality and should not be used in production yet! For this example I am using Percona Server 5.6 with the UDF.
That being said, the proof-of-concept that I’m about to present here uses only one JSON function (JSON_EXTRACT) and it has worked well enough in my testing to present my idea here. The JSON functions will probably be GA sometime soon anyway, and this is a useful test of the JSON_EXTRACT function. …

Last weekend I got to present to the MySQL Developers Room at
FOSDEM in Brussels.
The subject of my presentation was NoSQL and SQL the best
of both worlds…
There’s a lot of excitement around NoSQL Data Stores with the promise of simple access patterns, flexible schemas, scalability and High Availability. The downside comes in the form of losing ACID transactions, consistency, flexible queries and data integrity checks. What if you could have the best of both worlds? This session shows how MySQL Cluster provides simultaneous SQL and native NoSQL access to your data – whether a simple key-value API (Memcached), REST, JavaScript, Java or C++. You will hear how the MySQL Cluster architecture delivers in-memory real-time performance, 99.999% availability, on-line maintenance and linear, horizontal scalability …

Is it possible to turn Hadoop into a RDBMS? On this topic, I have interviewed Monte Zweben, Co-Founder and Chief Executive Officer of Splice Machine.

Q1. What are the main challenges of applications and operational analytics that support real-time, interactive queries on data updated in real-time for Big Data?
Monte Zweben: Let’s break down “real-time,
interactive queries on data updated in real-time for Big Data”.
“Real-time, interactive queries” means that results need to be
returned in milliseconds to a few seconds.
For “Data updated in real-time” to happen, …

In the word "NoSQL", the letters "No" are an acronym so the meaning is "Not Only SQL" rather than "No SQL". True or false?
Historically, it's false
The first NoSQL product was a classic DBMS which didn't happen to use SQL for a query language, featured in Linux Journal in 1999. Its current web page has a traffic-sign symbol of the word SQL with a bar through it, and a title "NoSQL: a non-SQL RDBMS".
For a meetup in June 2009 about "open source, distributed, non-relational databases" the question came up "What's a good name?" Eric Evans of Rackspace suggested NoSQL, a suggestion which …

I’ve enjoyed visiting Buenos Aires once a year for the MySQLNoSQLCloud event, put together by the awesome people at Binlogic (in particular, their proprietor Santiago Lertora). It’s happening again in 2014, which by my count is the third edition, and there’s a twist: Buenos Aires on 13 & 14 November, and Cordoba on 17 November. It’s never been held in Cordoba before (like an annex event), so I think this could be extremely exciting.
If you’re looking to speak, send Santiago a note at events@binlogic.com (or leave a message here). I’ll put you in touch with him. If you’re looking to sponsor, you get attendees from all over Latin America.
