-- 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
--     <https://docs.aws.amazon.com/qldb/latest/developerguide/getting-started-driver.html Getting started with the driver>
--     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
--     <https://docs.aws.amazon.com/qldb/latest/developerguide/data-shell.html Accessing Amazon QLDB using the QLDB shell>.
