When searching about NGSI and CartoDB integration, I came across three different components:
an NGSI connector to CartoDB: ("https://github.com/telefonicaid/fiware-orion2cartodb")
A CartoDB backend for Cygnus: ("http://fiware-cygnus.readthedocs.io/en/latest/cygnus-common/backendscatalogue/cartodbbackend/index.html")
An NGSI CartoDB sink: ("http://fiware-cygnus.readthedocs.io/en/latest/cygnus-ngsi/flumeextensionscatalogue/ngsicartodbsink/index.html")
Which component is used in which case? Are they used together? or separately for different cases? etc..
And are they used for live NGSI data as well as historic data? or one of the two only?
Thanks in advance for any clarifications.
