I found myself reading NoSQL is a Premature Optimization a few minutes ago and threw up in my mouth a little. That article is so far off base that I’m not even sure where to start, so I guess I’ll go in order.

In fact, I would argue that starting with NoSQL because you think you might someday have enough traffic and scale to warrant it is a premature optimization, and as such, should be avoided by smaller and even medium sized organizations.  You will have plenty of time to switch to NoSQL as and if it becomes helpful.  Until that time, NoSQL is an expensive distraction you don’t need.

Uhm… WHAT?!

I’ve spent more than a few years using MySQL and have been using some NoSQL systems for the last year or so in a fairly busy environment. And scaling is only one of the considerations that factor into …

I’ve released version 1.1.7 of the Better Cacti Templates project. This release includes a bunch of bug fixes, some new graphs for MySQL, and two new sets of graphs, for Redis graphing and for JMX graphing.

There are upgrade instructions on the project wiki for this and all releases. There is also a comprehensive tutorial on how to create your own graphs and templates with this project. Use the project issue tracker to view and report issues, and use the project mailing list to discuss the …

Persistence Smoothie: Blending NoSQL and SQL – see user feedback and comments at http://joind.in/talk/view/1332.

NoSQL is a new way to think about persistence. Most NoSQL systems are not ACID compliant (Atomicity, Consistency, Isolation, Durability).

Generally, most NoSQL systems have:

• Denormalization
  
• Eventual Consistency
  
• Schema-Free
  
• Horizontal Scale
  

NoSQL tries to scale (more) simply, it is starting to go mainstream – NY …

I wanted to compare the following DBs, NoSQLs and caching solutions for speed and connections. Tested the following

• Redis
• Memcached
• Tokyo Tyrant / Tokyo Cabinet
• MySQL 5.1.40 (MyISAM)
• MySQL 5.1.40 (with Innodb Plugin 1.0.4), compiled into source of MySQL

My test had the following criteria

• 2 client boxes
• All clients connecting to the server using Python
• Used Python's threads to create concurrency
• Each thread made 10,000 open-close connections to the server
• The server …

Key-value databases are catching fire these days. Memcached, Redis, Cassandra, Keyspace, Tokyo Tyrant, and a handful of others are surging in popularity, judging by the contents of my feed reader.

I find a number of things interesting about these tools.

• There are many more of them than open-source traditional relational databases. (edit: I mean that there are many options that all seem similar to each other, instead of 3 or 4 standing out as the giants.)
• It seems that a lot of people are simultaneously inventing solutions to their problems in private without being aware of each other, then open-sourcing the results. That points to a sudden sea change in architectures. Tipping points tend to be abrupt, which would explain isolated redundant development.
• Many of the products are feature-rich with things programmers need: diverse language bindings, APIs, embeddability, and the ability to speak familiar …
