Methods

#mutation_key

def mutation_key() -> ::Google::Cloud::Spanner::V1::Mutation

Returns

• (::Google::Cloud::Spanner::V1::Mutation) — Optional. Required for read-write transactions on a multiplexed session that commit mutations but do not perform any reads or queries. Clients should randomly select one of the mutations from the mutation set and send it as a part of this request. This feature is not yet supported and will result in an UNIMPLEMENTED error.

#mutation_key=

def mutation_key=(value) -> ::Google::Cloud::Spanner::V1::Mutation

Parameter

• value (::Google::Cloud::Spanner::V1::Mutation) — Optional. Required for read-write transactions on a multiplexed session that commit mutations but do not perform any reads or queries. Clients should randomly select one of the mutations from the mutation set and send it as a part of this request. This feature is not yet supported and will result in an UNIMPLEMENTED error.

#options

def options() -> ::Google::Cloud::Spanner::V1::TransactionOptions

Returns

• (::Google::Cloud::Spanner::V1::TransactionOptions) — Required. Options for the new transaction.

#options=

def options=(value) -> ::Google::Cloud::Spanner::V1::TransactionOptions

Parameter

• value (::Google::Cloud::Spanner::V1::TransactionOptions) — Required. Options for the new transaction.

Returns

• (::Google::Cloud::Spanner::V1::TransactionOptions) — Required. Options for the new transaction.

#request_options

def request_options() -> ::Google::Cloud::Spanner::V1::RequestOptions

Returns

• (::Google::Cloud::Spanner::V1::RequestOptions) — Common options for this request. Priority is ignored for this request. Setting the priority in this request_options struct will not do anything. To set the priority for a transaction, set it on the reads and writes that are part of this transaction instead.
