[keycloak-user] High throughput communication- Use of a transparent (by value) token

Hi, I have two backend servers that needs to communicate at a high throughput (1000s request per second). I don't want each of the requests to block/slow down by the server contacting the Keycloak server to verify the token. Is there a way, I can create a transparent token that could be verified without having to access the KeyCloak server in each request? Thanks, Omri.
