%% API
%%====================================================================

%% @doc Cancels a query that has been issued.
%%
%% Cancellation is provided only if the query has not completed running
%% before the cancellation request was issued. Because cancellation is an
%% idempotent operation, subsequent cancellation requests will return a
%% `CancellationMessage', indicating that the query has already been
%% canceled. See code sample for details.

%% @doc Create a scheduled query that will be run on your behalf at the
%% configured schedule.
%%
%% Timestream assumes the execution role provided as part of the
%% `ScheduledQueryExecutionRoleArn' parameter to run the query. You can
%% use the `NotificationConfiguration' parameter to configure
%% notification for your scheduled query operations.

%% @doc DescribeEndpoints returns a list of available endpoints to make
%% Timestream API calls against.
%%
%% This API is available through both Write and Query.
%%
%% Because the Timestream SDKs are designed to transparently work with the
%% service’s architecture, including the management and mapping of the
%% service endpoints, it is not recommended that you use this API unless:
%%
%% <ul> <li> You are using VPC endpoints (Amazon Web Services PrivateLink)
%% with Timestream
%%
%% </li> <li> Your application uses a programming language that does not yet
%% have SDK support
%%
%% </li> <li> You require better control over the client-side implementation
%%
%% </li> </ul> For detailed information on how and when to use and implement
%% DescribeEndpoints, see The Endpoint Discovery Pattern.

%% @doc A synchronous operation that allows you to submit a query with
%% parameters to be stored by Timestream for later running.
%%
%% Timestream only supports using this operation with the
%% `PrepareQueryRequest$ValidateOnly' set to `true'.

%% @doc `Query' is a synchronous operation that enables you to run a
%% query against your Amazon Timestream data.
%%
%% `Query' will time out after 60 seconds. You must update the default
%% timeout in the SDK to support a timeout of 60 seconds. See the code sample
%% for details.
%%
%% Your query request will fail in the following cases:
%%
%% <ul> <li> If you submit a `Query' request with the same client token
%% outside of the 5-minute idempotency window.
%%
%% </li> <li> If you submit a `Query' request with the same client token,
%% but change other parameters, within the 5-minute idempotency window.
%%
%% </li> <li> If the size of the row (including the query metadata) exceeds 1
%% MB, then the query will fail with the following error message:
%%
%% `Query aborted as max page response size has been exceeded by the output
%% result row'
%%
%% </li> <li> If the IAM principal of the query initiator and the result
%% reader are not the same and/or the query initiator and the result reader
%% do not have the same query string in the query requests, the query will
%% fail with an `Invalid pagination token' error.
%%
%% </li> </ul>
