#read_time ⇒ Google::Protobuf::Timestamp

Returns The consistent +read_time+ for the given +target_ids+ (omitted when the target_ids are not at a consistent snapshot).

The stream is guaranteed to send a +read_time+ with +target_ids+ empty whenever the entire stream reaches a new consistent snapshot. ADD, CURRENT, and RESET messages are guaranteed to (eventually) result in a new consistent snapshot (while NO_CHANGE and REMOVE messages are not).

For a given stream, +read_time+ is guaranteed to be monotonically increasing.

Returns:

  • (Google::Protobuf::Timestamp) —

    The consistent +read_time+ for the given +target_ids+ (omitted when the target_ids are not at a consistent snapshot).

    The stream is guaranteed to send a +read_time+ with +target_ids+ empty whenever the entire stream reaches a new consistent snapshot. ADD, CURRENT, and RESET messages are guaranteed to (eventually) result in a new consistent snapshot (while NO_CHANGE and REMOVE messages are not).

    For a given stream, +read_time+ is guaranteed to be monotonically increasing.

#resume_token ⇒ String

Returns A token that can be used to resume the stream for the given +target_ids+, or all targets if +target_ids+ is empty.

Not set on every target change.

Returns:

  • (String) —

    A token that can be used to resume the stream for the given +target_ids+, or all targets if +target_ids+ is empty.

#target_ids ⇒ Array<Integer>

Returns The target IDs of targets that have changed.

If empty, the change applies to all targets.

For +target_change_type=ADD+, the order of the target IDs matches the order of the requests to add the targets. This allows clients to unambiguously associate server-assigned target IDs with added targets.

For other states, the order of the target IDs is not defined.

Returns:

  • (Array<Integer>) —

    The target IDs of targets that have changed.

    If empty, the change applies to all targets.

    For +target_change_type=ADD+, the order of the target IDs matches the order of the requests to add the targets. This allows clients to unambiguously associate server-assigned target IDs with added targets.

    For other states, the order of the target IDs is not defined.
