Spring HTTP throttling request integration

Question

Looking at implementing restrictions on access to an HTTP request and I wonder if Poller is an option or should Interceptor be used? The idea has the rule "X number of requests / operations in the Y time interval" and should work through the cluster.

Answer 1

It depends on what you want to do for the throttled subscriber; throw an exception (after some timeout) or wait forever. Using the queue channel after the gateway (with a limit and send-timeouton the gateway) will work, and will throw an exception if the time is exceeded; setting the timeout to -1 (default) will be blocked forever.
