Question: what is the max concurrency I can set?

A lot of jobs are created, most of them have high I/O latency (up to a few seconds each) so I set the concurrency to 100 and 1000 on two workers as a way to avoid bottlenecks

if I set the concurrency to 20 then 20 jobs with a latency of 5 seconds will delay all other jobs

Is this applicable? How will it affect redis?

Thanks

The issue names no file, test, or entry point. Review Kue's worker concurrency setting and Redis-backed queue behavior first, then document the supported concurrency range and how high values affect Redis and delayed jobs.
