Onyx

What is it?

• a masterless, cloud scale, fault tolerant, high performance distributed computation system
• batch and stream hybrid processing model
• exposes an information model for the description and construction of distributed workflows
• Competes against Storm, Cascading, Cascalog, Spark, Map/Reduce, Sqoop, etc
• written in pure Clojure

What would I use this for?

• Realtime event stream processing
• Continuous computation
• Extract, transform, load
• Data transformation à la map-reduce
• Data ingestion and storage medium transfer
• Data cleaning

Official plugin listing

Official plugins are vetted by Michael Drogalis. Ensure in your project that plugin versions directly correspond to the same Onyx version (e.g. onyx-core-async version 0.9.1 goes with onyx version 0.9.1). Fixes to plugins can be applied using a 4th versioning identifier (e.g. 0.9.1.1).

• onyx-core-async
• onyx-kafka
• onyx-datomic
• onyx-redis
• onyx-sql
• onyx-bookkeeper
• onyx-seq
• onyx-durable-queue
• onyx-elasticsearch
• onyx-http
• onyx-amazon-sqs

Generate plugin templates through Leiningen with onyx-plugin.
