Redis Performance on EC2 (aka weekend project coming)

24 Apr 2009 10:26

Weekend is coming and I have a very small pet-project for it. I would still keep the idea non-public, but it involves processing hundreds of entries per second, analyzing data from multiple sources. It would have a dead-simple web interface.

The nature of the project requires really fast data backend, capable of storing and retrieving a few thousand items per second. The dataset would be approximately 5GB, average item size: 0.5KB.

When it came to tools selection, after short considerations I have chosen Sinatra for web interface, and Redis as a memory-only (with disk dumps) key-value datastore. It should be capable of handling 100 000 requests per second and deal well with large datasets, so fits perfectly. It also differs from Memcached or MemcachedDB because it has great higher-level structures like Lists and Sets, basic sorting and selection commands.

Today Amazon has announced another service, CloudFront — a damn easy to use Content Delivery Network.
