// SendCommand API operation for Amazon QLDB Session.
//
// 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).
//
// Returns awserr.Error for service API and SDK errors. Use runtime type assertions
// with awserr.Error's Code and Message methods to get detailed information about
// the error.
//
// See the AWS API reference guide for Amazon QLDB Session's
// API operation SendCommand for usage and error information.
//
// Returned Error Types:
//
//   - BadRequestException
//     Returned if the request is malformed or contains an error such as an invalid
//     parameter value or a missing required parameter.
//
//   - InvalidSessionException
//     Returned if the session doesn't exist anymore because it timed out or expired.
//
//   - OccConflictException
//     Returned when a transaction cannot be written to the journal due to a failure
//     in the verification phase of optimistic concurrency control (OCC).
//
//   - RateExceededException
//     Returned when the rate of requests exceeds the allowed throughput.
//
//   - LimitExceededException
//     Returned if a resource limit such as number of active sessions is exceeded.
//
//   - CapacityExceededException
//     Returned when the request exceeds the processing capacity of the ledger.
