A low-level client representing Amazon Timestream Query
import boto3
client = boto3.client('timestream-query')
These are the available methods:
Check if an operation can be paginated.
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.
See also: AWS API Documentation
Request Syntax
response = client.cancel_query(
QueryId='string'
)
[REQUIRED]
The ID of the query that needs to be cancelled. QueryID is returned as part of the query result.
{
'CancellationMessage': 'string'
}
Response Structure
A CancellationMessage is returned when a CancelQuery request for the query specified by QueryId has already been issued.
Exceptions
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.

[REQUIRED]
Name of the scheduled query.
[REQUIRED]
The query string to run. Parameter names can be specified in the query string @ character followed by an identifier. The named Parameter @scheduled_runtime is reserved and can be used in the query to get the time at which the query is scheduled to run.
The timestamp calculated according to the ScheduleConfiguration parameter, will be the value of @scheduled_runtime paramater for each query run. For example, consider an instance of a scheduled query executing on 2021-12-01 00:00:00. For this instance, the @scheduled_runtime parameter is initialized to the timestamp 2021-12-01 00:00:00 when invoking the query.
[REQUIRED]
The schedule configuration for the query.
An expression that denotes when to trigger the scheduled query run. This can be a cron expression or a rate expression.
[REQUIRED]
Notification configuration for the scheduled query. A notification is sent by Timestream when a query run finishes, when the state is updated or when you delete it.

This is to allow mapping column(s) from the query result to the dimension in the destination table.
This type is used to map column(s) from the query result to a dimension in the destination table.
Column name from query result.
Type for the dimension.
Multi-measure mappings.
The name of the target multi-measure name in the derived table. This input is required when measureNameColumn is not provided. If MeasureNameColumn is provided, then value from that column will be used as multi-measure name.

This field is autopopulated if not provided.
[REQUIRED]
The ARN for the IAM role that Timestream will assume when running the scheduled query.
A list of key-value pairs to label the scheduled query.
A tag is a label that you assign to a Timestream database and/or table. Each tag consists of a key and an optional value, both of which you define. Tags enable you to categorize databases and/or tables, for example, by purpose, owner, or environment.
The key of the tag. Tag keys are case sensitive.
The value of the tag. Tag values are case sensitive and can be null.
The Amazon KMS key used to encrypt the scheduled query resource, at-rest.

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 :

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:
See also: AWS API Documentation
Request Syntax
response = client.query(
QueryString='string',
ClientToken='string',
NextToken='string',
MaxRows=123
)
[REQUIRED]
The query to be run by Timestream.
Unique, case-sensitive string of up to 64 ASCII characters specified when a Query request is made. Providing a ClientToken makes the call to Query idempotent . This means that running the same query repeatedly will produce the same result. In other words, making multiple identical Query requests has the same effect as making a single request. When using ClientToken in a query, note the following:
This field is autopopulated if not provided.
A pagination token used to return a set of results. When the Query API is invoked using NextToken , that particular invocation is assumed to be a subsequent invocation of a prior call to Query , and a result set is returned. However, if the Query invocation only contains the ClientToken , that invocation of Query is assumed to be a new query run.
Note the following when using NextToken in a query:
The total number of rows to be returned in the Query output. The initial run of Query with a MaxRows value specified will return the result set of the query in two cases:
Otherwise, the initial invocation of Query only returns a NextToken , which can then be used in subsequent calls to fetch the result set. To resume pagination, provide the NextToken value in the subsequent command.
If the row size is large (e.g. a row has many columns), Timestream may return fewer rows to keep the response size from exceeding the 1 MB limit. If MaxRows is not provided, Timestream will send the necessary number of rows to meet the 1 MB limit.

[REQUIRED]
The query to be run by Timestream.
Unique, case-sensitive string of up to 64 ASCII characters specified when a Query request is made. Providing a ClientToken makes the call to Query idempotent . This means that running the same query repeatedly will produce the same result. In other words, making multiple identical Query requests has the same effect as making a single request. When using ClientToken in a query, note the following:
This field is autopopulated if not provided.
