> It would be useful to be able to perform snapshot reads at a timestamp that is higher than a client provided timestamp, thus improving recency, but lower that the server's oldest inflight transaction, thus minimizing the scan's chance to block.
> Such a mode would not guarantee linearizability, but would still allow for client-local read-your-writes, which seems to be one of the properties users care about the most.
> This should likely be the new default read mode for scanners.
