clearExactStaleness()
public TransactionOptions.ReadOnly.Builder clearExactStaleness() 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.

seconds. 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 the freshest data available at a nearby
replica, while bounding the possible staleness if the local
replica has fallen behind.
