// SendCommandRequest returns a request value for making API operation for
// Amazon QLDB Session.
//
// Sends a command to an Amazon QLDB ledger.
//
// Instead of interacting directly with this API, we recommend that you use
// the Amazon QLDB Driver or the QLDB Shell to execute data transactions on
// a ledger.
//
//    * If you are working with an AWS SDK, use the QLDB Driver. The driver
//    provides a high-level abstraction layer above this qldbsession data plane
//    and manages SendCommand API calls for you. For information and a list
//    of supported programming languages, see Getting started with the driver
//    (https://docs.aws.amazon.com/qldb/latest/developerguide/getting-started-driver.html)
//    in the Amazon QLDB Developer Guide.
//
//    * If you are working with the AWS Command Line Interface (AWS CLI), use
//    the QLDB Shell. The shell is a command line interface that uses the QLDB
//    Driver to interact with a ledger. For information, see Accessing Amazon
//    QLDB using the QLDB Shell (https://docs.aws.amazon.com/qldb/latest/developerguide/data-shell.html).
