"Apache Nifi is a new incubator project and was originally developed at the NSA. In short, it is a data flow management system similar to Apache Camel and Flume. It's mostly intended for getting data from a source to a sync. It can do light weight processing such as enrichment and conversion, but not heavy duty ETL. One unique feature of Nifi is its built-in UI, which makes the management and the monitoring of the data flow convenient. The whole data flow pipeline can be drawn on a panel. The UI shows statistics such as in/out byte rates, failures and latency in each of the edges in the flow. One can pause and resume the flow in real time in the UI. Nifi's Architecture is also a bit different from Camel and Flume. There is a master node and many slave nodes. The slaves are running the actual data flow and the master is for monitoring the slaves. Each slave has a web server, a flow controller (thread pool) layer, and a storage layer. All events are persisted to a local content repository. It also stores the lineage information in a separate governance repository, which allows it to trace at the event level. Currently, the fault tolerance story in Nifi is a bit weak. The master is a single point of failure. There is also no redundancy across the slaves. So, if a slave dies, the flow stops until the slave is brought up again." from http://www.confluent.io/blog/apachecon-2015/ http://www.confluent.io/blog/apachecon-2015/
