In our environment, I have two TYK gateway servers for load balancing, and the version of TYK is OSS v4.1. I would like to limit the number of concurrent requests for a specific API key on a particular endpoint (e.g., a maximum of 5 concurrent requests). I have checked that the rate limit does not meet our requirements, as it only controls how many requests an API consumer can make in a given period of time. Is there any method that can fulfill our request? If not, are there any alternatives?
I have provided the API key to a group of users. I would like to limit the concurrent connections to five for the corresponding endpoint when these users possess this API key.
