MediaTailor resources and operations requests are subject to the following quotas (formerly referred to as "limits").
You can use the AWSService Quotas service to view quotas and request quota increases for MediaTailor, as well as many other AWS services. For more information, see the Service Quotas User Guide.
Quotas on ad insertion
The following table describes the quotas on AWS Elemental MediaTailor ad insertion. Unless otherwise noted, the quotas are not adjustable.
| Name | Default quota value | Description |
|---|---|---|
| Ad decision server (ADS) length | 25,000 | The maximum number of characters in an ad decision server (ADS) specification. |
| Ad decision server (ADS) redirects | 5 | The maximum depth of redirects that MediaTailor follows in VAST wrapper tags. MediaTailor gives up if there are additional redirects. |
| Ad decision server (ADS) timeout | 3 | The maximum number of seconds that MediaTailor waits before timing out on an open connection to an ad decision server (ADS). When a connection times out due to no response from the ADS, MediaTailor is unable to fill the ad avail with ads. |
| Ad Insertion Requests | 10,000 | The maximum requests per second to make for personalized manifests
when performing server side ad insertion. Ad insertion handles incoming
requests for manifests, session initialization, tracking data, and ad
segments. This quota is adjustable |
| Configurations | 1,000 | The maximum number of configurations that MediaTailor allows. |
| Content origin length | 512 | The maximum number of characters in a content origin specification. |
| Content origin server timeout | 2 | The maximum number of seconds that MediaTailor waits before timing
out on an open connection to the content origin server when requesting
template manifests. Timeouts generate HTTP 504
(GatewayTimeoutException) response errors. |
| Manifest size | 2 | The maximum size, in MB, of any origin playback manifest. To ensure
that you stay under the quota, use gzip to compress your
input manifests into MediaTailor. |
| Package configurations | 5 | The maximum number of package configurations per source (whether live or video on demand). |
| Prefetch schedules | 25 | The maximum number of active prefetch schedules per playback configuration. Expired prefetch schedules don't count towards this limit. |
| 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. Session activity can be a
player request or an advance by the origin server. When the session
expires, MediaTailor returns an HTTP 400 (Bad Request)
response error. |
