I don't have benchmarks but multiple consumer groups are possible. For Kafka the performance should be similar or close to as having multiple consumers using a single group.

Say we have topic => ad_events .. I want to read events from ad_events topic and send it to two different systems... This can be achieved by creating two Consume Groups.. Example : Consumer Group SYS1 with 10 threads Consume Group SYS2 with 10 threads Would like to know having two different Consumer Groups will impact performance of Kafka Read ?? Also want to see the *Benchmarking Result*( Numbers ) of Single Topic Read with *One Consumer Group* Vs Single Topic with *Two/Three Consumer Group*.. Cheers, Senthil
