During a live stream, the client device continuously polls DAI for updates to the manifest. Since this may produce large quantities of duplicate served breaks, especially for high concurrency events or events with a long DVR window, Google Ad Manager tries to remove redundant log entries by using the following scheme:
- Served break logs are published every 5 minutes for each live stream.
- Each top level box represents a log file.
- Each row represents a manifest request from the client.
- Log entries are only published when the ad break is considered complete, that is when DAI has finished serving the expected duration of the ad break to a client.
- The green boxes indicate log entries that are published in the CSV file.
- Within that window we will publish the latest record of DAI serving each ad break.
- Logs are not de-duplicated across log files.
