readTime property
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.
Implementation
core.String? readTime;
