com.opencqrs.esdb.client.Option.FromLatestEvent

Record Components:

subject - the subject to read the latest event from

type - the Event.type() that the latest event must match

ifEventIsMissing - specifies the fall-back fetch strategy, in case there is no such event

All Implemented Interfaces:

Option

Enclosing interface:

Option

public static record Option.FromLatestEvent(String subject, String type, Option.FromLatestEvent.IfEventIsMissing ifEventIsMissing)
extends Record
implements Option

Specifies that the list of events is optimized by omitting any event prior to the latest event available for the subject specified as part of this.

This is typically used to read so-called snapshot events from the given subject location in favor of consuming a much longer event stream for the actual subject being fetched.
