Methods

#new_transaction

def new_transaction() -> ::Google::Cloud::Datastore::V1::TransactionOptions

Returns

• (::Google::Cloud::Datastore::V1::TransactionOptions) — Options for beginning a new transaction for this request.

  The new transaction identifier will be returned in the corresponding response as either LookupResponse.transaction or RunQueryResponse.transaction.

#new_transaction=

def new_transaction=(value) -> ::Google::Cloud::Datastore::V1::TransactionOptions

Parameter

• value (::Google::Cloud::Datastore::V1::TransactionOptions) — Options for beginning a new transaction for this request.

  The new transaction identifier will be returned in the corresponding response as either LookupResponse.transaction or RunQueryResponse.transaction.

Returns

• (::Google::Cloud::Datastore::V1::TransactionOptions) — Options for beginning a new transaction for this request.

  The new transaction identifier will be returned in the corresponding response as either LookupResponse.transaction or RunQueryResponse.transaction.

#read_consistency

def read_consistency() -> ::Google::Cloud::Datastore::V1::ReadOptions::ReadConsistency

Returns

• (::Google::Cloud::Datastore::V1::ReadOptions::ReadConsistency) — The non-transactional read consistency to use.

#read_consistency=

def read_consistency=(value) -> ::Google::Cloud::Datastore::V1::ReadOptions::ReadConsistency

Parameter

• value (::Google::Cloud::Datastore::V1::ReadOptions::ReadConsistency) — The non-transactional read consistency to use.

Returns

• (::Google::Cloud::Datastore::V1::ReadOptions::ReadConsistency) — The non-transactional read consistency to use.

#read_time

def read_time() -> ::Google::Protobuf::Timestamp

Returns

• (::Google::Protobuf::Timestamp) — Reads entities as they were at the given time. This value is only supported for Cloud Firestore in Datastore mode.

  This must be a microsecond precision timestamp within the past one hour, or if Point-in-Time Recovery is enabled, can additionally be a whole minute timestamp within the past 7 days.
