TimestreamQuery

Client

class TimestreamQuery.Client

A low-level client representing Amazon Timestream Query

client = session.create_client('timestream-query')

These are the available methods:

can_paginate(operation_name)

Check if an operation can be paginated.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Returns
True if the operation can be paginated, False otherwise.
cancel_query(**kwargs)

Cancels a query that has been issued. Cancellation is guaranteed only if the query has not completed execution 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 also: AWS API Documentation

Request Syntax

response = client.cancel_query(
    QueryId='string'
)
Parameters
QueryId (string) --

[REQUIRED]

The id of the query that needs to be cancelled. QueryID is returned as part of QueryResult.

Return type
dict
Returns
Response Syntax
{
    'CancellationMessage': 'string'
}

Response Structure

  • (dict) --
    • CancellationMessage (string) --

      A CancellationMessage is returned when a CancelQuery request for the query specified by QueryId has already been issued.

Exceptions

describe_endpoints()

DescribeEndpoints returns a list of available endpoints to make Timestream API calls against. This API is available through both Write and Query.

Because Timestream’s 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 :

  • Your application uses a programming language that does not yet have SDK support
  • You require better control over the client-side implementation

For detailed information on how to use DescribeEndpoints, see The Endpoint Discovery Pattern and REST APIs .

            'Address': 'string',
            'CachePeriodInMinutes': 123
        },
    ]
}

Response Structure

  • (dict) --
    • Endpoints (list) --

      An Endpoints object is returned when a DescribeEndpoints request is made.

      • (dict) --

        Represents an available endpoint against which to make API calls agaisnt, as well as the TTL for that endpoint.

        • Address (string) --

          An endpoint address.

        • CachePeriodInMinutes (integer) --

          The TTL for the endpoint, in minutes.

Exceptions

generate_presigned_url(ClientMethod, Params=None, ExpiresIn=3600, HttpMethod=None)

Generate a presigned url given a client, its method, and arguments

Parameters
  • ClientMethod (string) -- The client method to presign for
  • Params (dict) -- The parameters normally passed to ClientMethod.
  • ExpiresIn (int) -- The number of seconds the presigned url is valid for. By default it expires in an hour (3600 seconds)
  • HttpMethod (string) -- The http method to use on the generated url. By default, the http method is whatever is used in the method's model.
Returns

The presigned url

get_paginator(operation_name)

Create a paginator for an operation.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Raises OperationNotPageableError
Raised if the operation is not pageable. You can use the client.can_paginate method to check if an operation is pageable.
Return type
L{botocore.paginate.Paginator}
Returns
A paginator object.
get_waiter(waiter_name)

Returns an object that can wait for some condition.

Parameters
waiter_name (str) -- The name of the waiter to get. See the waiters section of the service docs for a list of available waiters.
Returns
The specified waiter object.
Return type
botocore.waiter.Waiter
query(**kwargs)

Query is a synchronous operation that enables you to execute a query. Query will timeout after 60 seconds. You must update the default timeout in the SDK to support a timeout of 60 seconds. The result set will be truncated to 1MB. Service quotas apply. For more information, see Quotas in the Timestream Developer Guide.

Request Syntax

response = client.query(
    QueryString='string',
    ClientToken='string',
    NextToken='string',
    MaxRows=123
)
Parameters
  • QueryString (string) --

    [REQUIRED]

    The query to be executed by Timestream.

  • ClientToken (string) --

    Unique, case-sensitive string of up to 64 ASCII characters that you specify when you make a Query request. Providing a ClientToken makes the call to Query idempotent, meaning that multiple identical calls have the same effect as one single call.

    Your query request will fail in the following cases:

    • If you submit a request with the same client token outside the 5-minute idepotency window.
    • If you submit a request with the same client token but a change in other parameters within the 5-minute idempotency window.

    After 4 hours, any request with the same client token is treated as a new request.

    This field is autopopulated if not provided.

  • NextToken (string) -- A pagination token passed to get a set of results.
  • MaxRows (integer) -- The total number of rows to return in the output. If the total number of rows available is more than the value specified, a NextToken is provided in the command's output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command.
