AvailMatchingCriteria

MediaTailor only places (consumes) prefetched ads if the ad break meets the criteria defined by the dynamic variables. This gives you granular control over which ad break to place the prefetched ads into.

As an example, let's say that you set DynamicVariable to scte.event_id and Operator to EQUALS, and your playback configuration has an ADS URL of https://my.ads.server.com/path?&podId=[scte.avail_num]&event=[scte.event_id]&duration=[session.avail_duration_secs]. And the prefetch request to the ADS contains these values https://my.ads.server.com/path?&podId=3&event=my-awesome-event&duration=30. MediaTailor will only insert the prefetched ads into the ad break if has a SCTE marker with an event id of my-awesome-event, since it must match the event id that MediaTailor uses to query the ADS.

You can specify up to five AvailMatchingCriteria. If you specify multiple AvailMatchingCriteria, MediaTailor combines them to match using a logical AND. You can model logical OR combinations by creating multiple prefetch schedules.
