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.

clearMaxStaleness()
public TransactionOptions.ReadOnly.Builder clearMaxStaleness() Read data at a timestamp >= NOW - 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.
Note that this option can only be used in single-use transactions.

clearMinReadTimestamp()
public TransactionOptions.ReadOnly.Builder clearMinReadTimestamp() Executes all reads at a timestamp >= min_read_timestamp.
This is useful for requesting fresher data than some previous read, or data that is fresh enough to observe the effects of some previously committed transaction whose timestamp is known.
Note that this option can only be used in single-use transactions.
A timestamp in RFC3339 UTC \"Zulu\" format, accurate to nanoseconds.
Example: "2014-10-02T15:01:23.045123456Z".

clearReadTimestamp()
public TransactionOptions.ReadOnly.Builder clearReadTimestamp()Executes all reads at the given timestamp. Unlike other modes, reads at a specific timestamp are repeatable; the same read at the same timestamp always returns the same data. If the timestamp is in the future, the read will block until the specified timestamp, modulo the read's deadline.
Useful for large scale consistent reads such as mapreduces, or for coordinating many reads against a consistent snapshot of the data.
A timestamp in RFC3339 UTC \"Zulu\" format, accurate to nanoseconds.
Example: "2014-10-02T15:01:23.045123456Z".
