Interface IEventMetadata
- Assembly
- Diffusion.Client.dll
The time series event metadata.
public interface IEventMetadataRemarks
Added in version 6.1.
Properties
Author
Gets the server-authenticated identity of the session that created the event.
string Author { get; }Property Value
- string
The principal that created the event, or Empty if the session that created the event was not authenticated.
Sequence
Gets the sequence number identifying this event within its time series.
long Sequence { get; }Property Value
- long
The non-negative sequence number.
Remarks
Assigned by the server when the event is created.
Sequence numbers are unique within a time series. Each event appended to a time series is assigned a sequence number that is equal to the sequence number of the preceding event plus one.
Timestamp
Gets the event timestamp.
long Timestamp { get; }Property Value
- long
The difference, measured in milliseconds, between the time the server added the event to the time series and midnight, January 1, 1970 UTC.
Remarks
Assigned by the server when the event is created.
Events do not have unique timestamps. Events with different sequence numbers may have the same timestamp.
Subsequent events in a time series usually have timestamps that are greater or equal to the timestamps of earlier events, but this is not guaranteed due to changes to the time source used by the server.
