The structural properties of a stream.

public enum StreamStructure

Fields

EDIT_EVENT_STREAM = 1

The stream is presented in time series order.

The stream has the following properties:

• The sequence of each event in the stream is unique.
• The stream is ordered by sequence. The sequence of each subsequent event in the stream is greater than its predecessor.
• Edit event timestamps may lie outside the query range.
• The stream can have multiple edit events for the same original event.

VALUE_EVENT_STREAM = 0

The stream is ordered by the original event sequence number, presenting edit events instead of the original events they replace.

The original event sequence number of an event e is e.OriginalMetadata.Sequence. It is equal to e.Sequence, if and only if e is an original event.

The stream has the following properties:

• The sequence of each event in the stream is unique.
• The original event sequence of each event in the stream is unique.
• The stream is ordered by original event sequence. The original event sequence of each subsequent event in the stream is greater than its predecessor.
• If no events have been removed from the time series, the original event sequence of each subsequent event is one greater than its predecessor.
• If an event is an original event, the query found no corresponding edit events.
• If an event is an edit event, its timestamp attribute may lie outside the query range. Consequentially, the sequence and timestamp attributes of the events may be non-sequential.
