Hi, of course there are :) So the transformations are deployed in a separate NodeJs process per node. You can use familiar tools to take a look at its cpu + memory usage.
As for how it affects redpanda, currently we are working on exposing metrics via Prometheus. All of this work occurs on background threads, so the only way it would affect throughput is if enough coprocessors are deployed with enough actual work that would eventually start to fill up our seastar reactors.
