Reads events from the selected branch and space by sequence range. The start sequence is inclusive and the optional end sequence is exclusive; reverse direction walks backward from the start sequence. An optional event type narrows the results.

Paginated responses use opaque cursors. Clients should pass the returned cursor back to the same command shape and must not parse cursor contents.

Examples

Read a range of events by sequence.

CLI

$ strata event append user.created {"id":1}
$ strata event append user.updated {"id":2}
$ strata event range 0 forward

Wire

{"event_type":"user.created","payload":{"id":1},"type":"event_append"}
{"event_type":"user.updated","payload":{"id":2},"type":"event_append"}
{"direction":"forward","start_seq":0,"type":"event_range"}

Parameters

Name	Type	Required	Description
direction	EventRangeDirection	yes	Result ordering.
end_seq	integer	no	Optional exclusive end sequence; with reverse direction, exclusive lower bound.
event_type	string	no	Optional event type filter.
limit	integer	no	Optional item limit.
start_seq	integer	yes	Inclusive start sequence; with reverse direction, walk backward from this sequence.

Plus the optional scope: branch and space (default to the session branch and the "default" space).

Returns

Page<EventVersionedData, u64>.
