Description Learn how to consume real-time data from the Satori RTM platform using NiFi. Background Satori is a cloud-based live platform that provides a publish-subscribe messaging service called RTM, and also makes available a set of free real-time data feeds as part of their Open Data Channels initiative: https://www.satori.com/docs/using-satori/overview https://www.satori.com/opendata/channels This article steps through how to consume from Satori's Open Data Channels in NiFi, using a custom NiFi processor. Note - the article assumes you already have a working version of NiFi up and running. Link to code on github: https://github.com/laurencedaluz/nifi-satori-bundle Installing the custom processor To create the required nar file, simply clone and build the following repo with maven: git clone https://github.com/laurencedaluz/nifi-satori-bundle.git cd nifi-satori-bundle mvn clean install This will make the following .nar file under the nifi-satori-bundle-nar/target/ directory: nifi-satori-bundle-nar-<version>.nar Copy this file into the lib directory of your NiFi instance. If using HDF, it exists at: /usr/hdf/current/nifi/lib Restart NiFi for the nar to be loaded. Using the ConsumeSatoriRtm processor The ConsumeSatoriRtm accepts the following configurations: At a minimum, you will just need to provide the following configurations (which you can get directly from the satori open channels site): Endpoint Appkey Channel In this example, I've chosen to consume from the 'big-rss' feed using the configurations provided here: https://www.satori.com/opendata/channels/big-rss That's it! after starting the ConsumeSatoriRtm process you will see data flowing: Additional Features The processor also supports using Satori's Streamview filters, which allow you to provide SQL-like queries to select, transform, or aggregate messages from a subscribed channel: In the 'big-rss' example above, the following filter configuration would limit the stream to messages containing the word "jobs". select * from `big-rss` where feedURL like '%jobs%' The NiFi processor also supports batching of multiple messages into a single FlowFile, which will provide a new-line delimited list of messages in each file (based on a 'minimum batch size' configuration): ...
