Instance Attribute Details

#exclude_txn_from_change_streams ⇒ Boolean Also known as: exclude_txn_from_change_streams?

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. Corresponds to the JSON property excludeTxnFromChangeStreams

Returns:

  • (Boolean)
