Node.js, RabbitMQ, and AccumuloJosh Elser 2012-05-03, 01:46
A while back, I wrote some code as a proof of concept to use node.js (an
event-driven, server-side Javascript environment) as a way to ingest data into Accumulo. I think it's a cool example of alternative ways to get data into Accumulo, so I cleaned up what I wrote and posted it to Github. https://github.com/joshelser/node-accumulo Using RabbitMQ (open source message broker which implements the AMQP standard) and a node.js plugin for AMQP, I was able to send data from a node.js process, through RabbitMQ, into a background Java process which inserts the data into Accumulo. The example is a contrived website hit-tracking application (think Google Analytics). When a user visits a website, an HTTP request -- with the client IP, server IP, and current timestamp in the query string -- is made to an HTTP server running inside of the node.js process. This information then makes its way into Accumulo as a key-value pair. I hope to expand on this some more, but I wanted to share the existing concept with everyone. Instructions and additional information can be found on the project page. Feedback is welcome! - Josh |
