Response message for SubscriptionService.SubscribeCheckpoints.
A checkpoint stream's position is checkpoint-granular, so the cursor sequence number stands in for the Watermark message the other subscription responses carry. Progress-only frames (with checkpoint unset) occur only on filtered streams: on an unfiltered stream every frame carries both fields, in order and without gaps.
Properties
The matching checkpoint. Unset when this frame only advances the cursor past non-matching checkpoints.
Required. The checkpoint sequence number the stream has fully covered, inclusive: every matching checkpoint from the stream's start position through cursor has been delivered. Present on every frame and advances monotonically.
Returns the field-presence view for this SubscribeCheckpointsResponse instance.
