Draco - Data Persistence using Apache NIFI
Draco is a connector in charge of persisting context data sources into other third-party databases and storage systems, creating a historical view of the context. Internally, Draco is based on Apache NiFi. NiFi is a popular framework for data management and processing from multiple sources.
Draco plays the role of a connector between the Orion Context Broker (which is an NGSI source of data) source of data) and a wide range of external systems such as MySQL, MongoDB etc. You can use Draco if you need to process and persist context data so that you can keep a historical record. Draco can also be used to filter and repost context data back into Orion.
Data Persistence using Draco is described in the following step-by-step tutorial:
