Data queries execution
Execute a single data query outside of transactions. Query parameters are passed in Args as "string key - value" pairs: client.ExecuteDataQuery(query, "name1", value1, "name2", value2, ...); Use ydb::PreparedArgsBuilder for storing a generic buffer of query params if needed.

BulkUpsert()

template<typename RangeOfStructs >

void ydb::TableClient::BulkUpsert	(	std::string_view	table,
		const RangeOfStructs &	rows,
		OperationSettings	settings = {} )

Efficiently write large ranges of table data. The passed range of structs is serialized to TValue.
