ReadOnly class
Message type to initiate a read-only transaction.
Constructors
- ReadOnly()
- ReadOnly.fromJson(Map _json)
Properties
- exactStaleness ↔ String
-
Executes all reads at a timestamp that is
exact_stalenessold. The timestamp is chosen soon after the read is started. [...]read / write - maxStaleness ↔ String
-
Read data at a timestamp >=
NOW - max_stalenessseconds. 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. [...]read / write - minReadTimestamp ↔ String
-
Executes all reads at a timestamp >=
min_read_timestamp. [...]read / write - readTimestamp ↔ String
-
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. [...]
read / write

read / write
- strong ↔ bool
-
Read at a timestamp where all previously committed transactions
