Fixtures Push API v2 is a pub/sub or message queue mechanism for distributing updates in real time. The produced contracts are described in the Read Data Points section of each document under the Domain Entities document.
Fixture push v2 uses the same contracts as Fixtures API v2, thus the API Swagger is also relevant for the push users to get a good understanding of the models they need. If going for the swagger take the /GET methods and see all “{Entity}ResponseModel” - e.g. FixtureResponseModel, CompetitionResponseModel etc.
The Fixtures Push API v2 has a simple architecture that listens for updates made in the Fixtures platform and then publishes them to a third-party real-time provider called Ably for consumption from the subscribers/consumers of the specific channels/queue.
Ably basically provide 2 options for the consumption of the messages.

Pub/Sub is less fault tolerant, it only has 2 minutes of a window to keep to messages in client is not listening - the good news is that what is missed can be from ably history api up to 72h.
Pub/Sub. Getting what is missed from the history API makes the overall integration a bit more complex
Pub/Sub. Another option to get what is missed to bootstrap from Fixtures API v2
Pub/Sub requires the client to use the whole channel to subscribe to e.g. Fixtures.10.19 - this subscribes to football fixtures only for the Champions league
Firehose is fault tolerant by design as provide mechanisms to ensure reliable delivery, even in the presence of failures or intermittent connectivity issues
Firehose requires provisioning of infrastructure on the client which is connected by the Genius Sports team - however, this makes the solution more costly
Firehose can have wildcards on a subscription base thus having an integration Fixtures.10.* for all football fixtures, or even for all fixtures - Fixtures.*.*
Furthermore, this feature can have the significant benefit of reducing the complexity on the client by also supporting regex expressions, so if we assume that the client is interested only in a few specific entities for some concrete sports it can be easily achieved - (Competitions|Fixtures).(10|17).* will account for all competition and fixtures entities for Football and American Football.
