A stream of the persistent events that have the given aggregateTag
, e.g.
A stream of the persistent events that have the given aggregateTag
, e.g.
all persistent events of all Order
entities.
The type of the offset is journal dependent, some journals use time-based
UUID offsets, while others use sequence numbers. The passed in fromOffset
must either be Offset#NONE, or an offset that has previously been produced
by this journal.
The stream will begin with events starting after fromOffset
.
To resume an event stream, store the Offset
corresponding to the most
recently processed Event
, and pass that back as the value for
fromOffset
to start the stream from events following that one.
IllegalArgumentException
If the fromOffset
type is not supported
by this journal.

This method will only work with journals that support UUID offsets. Journals that produce sequence offsets will fail during stream handling.
