Name Default quota value Description
Ad decision server (ADS) length 25,000 The maximum number of characters in an ad decision server (ADS) specification.

Server side reporting beacon request timeout 3 seconds The maximum number of seconds that MediaTailor waits before timing out on an open connection to the server when firing a beacon for server side reporting. When a connection times out, MediaTailor is unable to fire the beacon and the service logs an ERROR_FIRING_BEACON_FAILED message to the MediaTailor/AdDecisionServerInteractions log in CloudWatch.
Session expiration 10 times the manifest duration The maximum amount of time that MediaTailor allows a session to remain inactive before ending the session.
