> The Java client could use a mode called "read your writes" consistency where we ensure that we read whatever the leader has committed at the time of the request.
> At the time of writing, the implementation requirements look like the following:
> * Always scan from the leader
> * Specify that the leader must apply all operations from previous leaders before processing the query
> In the C++ client, this can be achieved by specifying both of the LEADER_ONLY and READ_AT_SNAPSHOT options, while not specifying a timestamp to use for the snapshot when starting the scan.
> In the Java client API, we may want to simply expose a scan option called "read your writes" or something similar.
