Parameters
Name Description
data array

Optional. Data for populating the Message object.
↳ read_write TransactionOptions\ReadWrite

Transaction may write. Authorization to begin a read-write transaction requires spanner.databases.beginOrRollbackReadWriteTransaction permission on the session resource.
↳ partitioned_dml TransactionOptions\PartitionedDml

Partitioned DML transaction. Authorization to begin a Partitioned DML transaction requires spanner.databases.beginPartitionedDmlTransaction permission on the session resource.
↳ read_only TransactionOptions\PBReadOnly

Transaction does not write. Authorization to begin a read-only transaction requires spanner.databases.beginReadOnlyTransaction permission on the session resource.
↳ exclude_txn_from_change_streams bool

When exclude_txn_from_change_streams is set to true, it prevents read or write transactions from being tracked in change streams. * * If the DDL option allow_txn_exclusion is set to true, then the updates made within this transaction aren't recorded in the change stream. * * If you don't set the DDL option allow_txn_exclusion or if it's set to false, then the updates made within this transaction are recorded in the change stream. When exclude_txn_from_change_streams is set to false or not set, modifications from this transaction are recorded in all change streams that are tracking columns modified by these transactions. The exclude_txn_from_change_streams option can only be specified for read-write or partitioned DML transactions, otherwise the API returns an INVALID_ARGUMENT error.
↳ isolation_level int

Isolation level for the transaction.
