It seems obvious that given the decreasing cost of storage and computation, there's going to be a significant increase in the volume of data that organizations accumulate over the next 10 years. But the type of data being accumulated may be different from the areas where traditional DBMSs dominated. It's not just about transactions; it's search patterns, on-line behavior, click-thru data, events fired off by smartphones, messages over Twitter & Facebook, log data of various kinds.
If an organization can figure out a better way identify prospects, or deliver more targeted ads, or optimize pricing decisions by analyzing terrabytes of data, they'd be crazy not to. Over the long term, companies that don't develop these capabilities will be at a competitive disadvantage.
As to what the implications are from a …[Read more]

This miniconf aims to cover many of the current methods of data storage and retrieval and attempt to bring order to the universe. We’re aiming to cover what various systems do, what the latest developments are and what you should use for various applications.
We aim for talks from developers of and developers using the software in question.
Aiming for some combination of: PostgreSQL, Drizzle, MySQL, XFS, ext, Swift (open source cloud storage, part of OpenStack), memcached, TokyoCabinet, TDB/CTDB, CouchDB, MongoDB, Cassandra, HBase….. and more!
I'm the boards of two companies (Pentaho, Revolution Analytics) that are starting to see a lot of customer traction around Big Data. More and more companies in media, pharma, retail and finance are doing advanced analysis, reporting, graphing, etc with massive data sets. It made me wonder what other areas of the technology stack might evolve with the trend towards Big Data. Obviously, there's new middleware layers like Hadoop and Map Reduce, and we're also seeing the emergence of NoSQL data management layers with Cassandra, MongoDB, MemBase and others. But what …[Read more]
Ever since Digg launched its new site design, it’s been plagued with all kinds of trouble, not least of which is that it keeps going down. The problems with the new architecture are so bad that VP of Engineering John Quinn is now gone, we’ve confirmed with sources close to Digg.
In a Diggnation video today, CEO Kevin Rose explained some of the technical issues the site is dealing with and why it can’t simply roll back to the previous architecture. The new version of Digg, v4, is based on a distributed database called Cassandra, which replaced the MySQL database the site ran on before. Cassandra is very advanced—it is supposed to be faster and scale …[Read more]
I finally got some time to do some house cleaning. One of my nagging low-hanging fruit jobs was to stop using jconsole as my monitor. I created a ganglia script to graph what is above. The image illustrated above I am showing all the Cassandra servers and their total row read stages completed in the last hour as a gauge. In essence I am graphing the delta of the change between ganglia script runs.
How I have it set up is:
All data exposed by JMX to produce tpstats and cfstats is graphed via ganglia. The pattern for each graph is as follows
stat_class - tpc, tpp, tpa means complete, pending, active respectively
key - would be message deserialization for instance.
For column family stats I graph the keyspace stats as well as the specific column family …
In addition to the Boston edition, there’s an OpenSQL Camp at the same time and place as FrOSCon mid-August in Germany. The call for papers is open until July 11th. As always, the conference is about all kinds of open-source databases: MySQL and PostgreSQL are only two of the obvious ones; MongoDB and Cassandra featured prominently at the last one I attended, and SQLite was well represented at the first one.
