Hello there, I am talking on behalf of the New Generation Internet Research gropu of Universidad Politécnica de Madrid and as member of FIWARE Community. In the last years, we have been working on custom NiFi's processors for providing NGSI-LD support for data persistence in different storage systems. We already have many processors ready for this purpose and we have the intention to contribute these developments to NiFi project. We have created the ticket in Jira NIFI-8472 <https://issues.apache.org/jira/browse/NIFI-8472> with more information about it. It is possible that we can start a discussion for analyzing the possibility of contributing this code?
BR, Andrés Muñoz
