exactStaleness property
Executes all reads at a timestamp that is exact_staleness old.
The timestamp is chosen soon after the read is started. Guarantees that
all writes that have committed more than the specified number of seconds
ago are visible. Because Cloud Spanner chooses the exact timestamp, this
mode works even if the client's local clock is substantially skewed from
Cloud Spanner commit timestamps. Useful for reading at nearby replicas
without the distributed timestamp negotiation overhead of max_staleness.
