query

Description

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:

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

See 'aws help' for descriptions of global parameters.

query is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: Rows

Synopsis

  query
--query-string <value>
[--client-token <value>]
[--cli-input-json <value>]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--query-string (string)

The query to be run by Timestream.

--client-token (string)

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:

  • If the Query API is instantiated without a ClientToken , the Query SDK generates a ClientToken on your behalf.
  • If the Query invocation only contains the ClientToken but does not include a NextToken , that invocation of Query is assumed to be a new query run.
  • If the invocation contains NextToken , that particular invocation is assumed to be a subsequent invocation of a prior call to the Query API, and a result set is returned.
  • After 4 hours, any request with the same ClientToken is treated as a new request.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command's output. If the total number of items 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. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.
