    Query events for given slices.

    Query events for given slices. A slice is deterministically defined based on the persistence id. The purpose is to evenly distribute all persistence ids over the slices.

    The consumer can keep track of its current position in the event stream by storing the offset and restart the query from a given offset after a crash/restart.

    The supported offset is TimestampOffset and Offset.noOffset.

    The timestamp is based on the database transaction_timestamp() when the event was stored. transaction_timestamp() is the time when the transaction started, not when it was committed. This means that a "later" event may be visible first and when retrieving events after the previously seen timestamp we may miss some events. In distributed SQL databases there can also be clock skews for the database timestamps. For that reason it will perform additional backtracking queries to catch missed events. Events from backtracking will typically be duplicates of previously emitted events. It's the responsibility of the consumer to filter duplicates and make sure that events are processed in exact sequence number order for each persistence id. Such deduplication is provided by the R2DBC Projection.

    Events emitted by the backtracking don't contain the event payload (EventBySliceEnvelope.event is None) and the consumer can load the full EventBySliceEnvelope with R2dbcReadJournal.loadEnvelope.

    The events will be emitted in the timestamp order with the caveat of duplicate events as described above. Events with the same timestamp are ordered by sequence number.

    The stream is not completed when it reaches the end of the currently stored events, but it continues to push new events when new events are persisted. Corresponding query that is completed when it reaches the end of the currently stored events is provided by R2dbcReadJournal.currentEventsBySlices.
