I'm currently running benchmarks using ESRally with a distributed setup for the load test driver. When distributing the load test driver, are search operations also split across the different nodes/drivers?
Hi Rafael, welcome back 
In a distributed setup, Rally splits the workload to multiple load drivers according to the number of clients. In other words, if N number of clients has been designated to a search operation, then you can expect Rally to divide N by the number of load drivers to handle search requests.
Thank you,
Jason
