Read at a timestamp where all previously committed transactions are visible.

Read at a timestamp where all previously committed transactions are visible.
bool strong = 1;getStrong in interface TransactionOptions.ReadOnlyOrBuilderpublic boolean hasMinReadTimestamp()
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"`.

.google.protobuf.Timestamp min_read_timestamp = 2;getMinReadTimestampOrBuilder in interface TransactionOptions.ReadOnlyOrBuilderpublic boolean hasMaxStaleness()
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.
.google.protobuf.Duration max_staleness = 3;hasMaxStaleness in interface TransactionOptions.ReadOnlyOrBuilderpublic Duration getMaxStaleness()
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.

.google.protobuf.Duration max_staleness = 3;getMaxStalenessOrBuilder in interface TransactionOptions.ReadOnlyOrBuilderpublic boolean hasReadTimestamp()
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"`.

.google.protobuf.Timestamp read_timestamp = 4;getReadTimestampOrBuilder in interface TransactionOptions.ReadOnlyOrBuilderpublic boolean hasExactStaleness()
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`.

If true, the Cloud Spanner-selected read timestamp is included in the [Transaction][google.spanner.v1.Transaction] message that describes the transaction.
