// Sends a command to an Amazon QLDB ledger. Instead of interacting directly with
// this API, we recommend using the 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 QLDB Session 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)
