--
-- The transactional data APIs for Amazon QLDB
--
-- 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>.

-- $errors
-- Error matchers are designed for use with the functions provided by
-- <http://hackage.haskell.org/package/lens/docs/Control-Exception-Lens.html Control.Exception.Lens>.
-- This allows catching (and rethrowing) service specific errors returned
-- by 'QLDBSession'.

-- $operations
-- Some AWS operations return results that are incomplete and require subsequent
-- requests in order to obtain the entire result set. The process of sending
-- subsequent requests to continue where a previous request left off is called
-- pagination. For example, the 'ListObjects' operation of Amazon S3 returns up to
-- 1000 objects at a time, and you must send subsequent requests with the
-- appropriate Marker in order to retrieve the next page of results.
--
-- Operations that have an 'AWSPager' instance can transparently perform subsequent
-- requests, correctly setting Markers and other request facets to iterate through
-- the entire result set of a truncated API operation. Operations which support
-- this have an additional note in the documentation.
--
-- Many operations have the ability to filter results on the server side. See the
-- individual operation parameters for details.

-- $waiters
-- Waiters poll by repeatedly sending a request until some remote success condition
-- configured by the 'Wait' specification is fulfilled. The 'Wait' specification
-- determines how many attempts should be made, in addition to delay and retry strategies.
