Pushing ``[TODO]``

Pushing ``[Draft]``
|
||||
~~~~~~~~~~~~~~~~~~~
|
||||
This API is called by the HS when the HS wants to push an event (or batch of
|
||||
events) to the AS.
|
||||
|
||||
- Retry semantics
|
||||
- Ordering
|
||||
Inputs:
|
||||
- HS Credentials
|
||||
- Event(s) to give to the AS
|
||||
- HS-generated transaction ID
|
||||
Output:
|
||||
- None.
|
||||
|
||||
Data flows:
|
||||
|
||||
::
|
||||
|
||||
Typical
|
||||
HS ---> AS : Home server sends events with transaction ID T.
|
||||
<--- : AS sends back 200 OK.
|
||||
|
||||
AS ACK Lost
|
||||
HS ---> AS : Home server sends events with transaction ID T.
|
||||
<-/- : AS 200 OK is lost.
|
||||
HS ---> AS : Home server retries with the same transaction ID of T.
|
||||
<--- : AS sends back 200 OK. If the AS had processed these events
|
||||
already, it can NO-OP this request (and it knows if it is the same
|
||||
events based on the transacton ID).
|
||||
|
||||
|
||||
Retry notes:
|
||||
- If the HS fails to pass on the events to the AS, it must retry the request.
|
||||
- Since ASes by definition cannot alter the traffic being passed to it (unlike
|
||||
say, a Policy Server), these requests can be done in parallel to general HS
|
||||
processing; the HS doesn't need to block whilst doing this.
|
||||
- Home servers should use exponential backoff as their retry algorithm.
|
||||
- Home servers MUST NOT alter (e.g. add more) events they were going to
|
||||
send within that transaction ID on retries, as the AS may have already
|
||||
processed the events.
|
||||
|
||||
Ordering notes:
|
||||
- The events sent to the AS should be linearised, as they are from the event
|
||||
stream.
|
||||
- The home server will need to maintain a queue of transactions to send to
|
||||
the AS.

Examples
|

--------
|

.. NOTE::
|
||||
- User/Alias namespaces are subject to change depending on ID conventions.
|
||||
- Should home servers by default generate fixed room IDs which match the room
|
||||
alias? Otherwise, you need to tell the AS that room alias X matches room ID
|
||||
Y so when the home server pushes events with room ID Y the AS knows which
|
||||
room that is.
