The Event Feed API automatically exposes a unique feed of events for each aggregate type that you can use to build queryable data or implement side-effects to connect your system to other services.
When an event batch is persisted in the store it is assigned a sequence number. Each feed has its own ever increasing sequence number. This number is what the feed subscribers use to keep track of how much of the feed has been consumed. The number is guaranteed to be a unique, ever increasing, positive integer.
The API includes a special endpoint called
_all that returns events for all aggregate types, in insertion order.
Simply pass a zero, or exclude the parameter from the request to receive everything since the beginning.
sequenceNumber of the last received event as a
since parameter to limit the response to only include
events since then.
It’s possible to get all events within a given period by specifying the from/to date/time range.
Default value for
