Hello,

Recently working on some Kafka integrations with Node-RED flows and found out that if I am having N number of flows, all of which are using kafka consumer node, it's not possible to connect and use all of them in parallel.

I can connect only one flow to a kafka topic at a time! It seems the single thread is getting used by the consumer at the time when its connected, so since we don't have multi threads here, achieving multiple consumer connections is not possible on a single node-red instance.

Am I right ?

Thanks in advance,  
Gaurav

It might be useful to indicate [which node](https://flows.nodered.org/search?term=kafka) you are using?  
As well as trying other nodes, it may be worth raising an issue on the nodes repository.
