NoSQL: Thoughts from NoSQL Evening in Palo Alto

Thoughts from NoSQL Evening in Palo Alto

I should start by saying that I love new technology as long as it proves to be useful and that it works. For example I've been using LiveScribe to record the great NoSQL Evening in Palo Alto event organized by Tim Anglade with InfiniteGraph support, just to discover later that it decided to lose everything. So, instead of being able to quote things from the event, I'll have to rely on my memory, which is really really bad.

Redisql: Redis with Extensive SQL Flavor

So I wrote Redisql which is an extension of redis that also supports a large subset of SQL. […] Redisql supports all redis data types and functionality (as it's an extension of redis) and it also supports SQL SELECT/INSERT/UPDATE/DELETE (including joins, range-queries, multiple indices, etc…) -> lots of SQL, short of stuff like nested joins and Datawarehousing functionality (e.g. FOREIGN KEY CONSTRAINTS). So using a Redisql library (in your environment's native language), you can either call redis operations on redis data objects or SQL operations on relational tables, its all in one server accessed from one library.

This guide was written for Cygwin 1.7.7, Hadoop 0.21.0 and HBase 0.20.6. You will additionally need ZooKeeper 3.3.1 in order to get HBase to run properly.

NoSQL: Will Scalable Data Stores Make NoSQL a Non-Starter?

Will Scalable Data Stores Make NoSQL a Non-Starter?

Once we're no longer talking about serving data, but rather just about storing large volumes of it, NoSQL can seem nearly obsolete. For organizations willing to pay for data warehousing and analysis tools, the options are limitless: massively parallel software, data warehouse appliances, distributed file systems, and the list goes on. Pick your poison. Have lots of unstructured data to analyze and don't want to pay for software? Try Hadoop. Plus, it might very well work with your existing data management software.
