public class ExecuteRequest extends CommonRequest
A request issued by the application to perform an operation (e.g., UPDATE, CREATE, READ, etc.) on a specific collection of a keySpace. the request receives information about the keySpace and collection identifiers, as well as an object containing the information about the operation to be executed. The operation is represented to a CommonOperation abstract class that can be instantiated through different types of operations for specific storage solutions (i.e., Blockchain, RDBMS, etc.). For more informations check the storage.utils.operation package.
