  your AWS secret access key.

• sessionToken (AWS.Credentials) —

  the optional AWS session token to sign requests with.

• credentials (AWS.Credentials) —

  the AWS credentials to sign requests with. You can either specify this object, or specify the accessKeyId and secretAccessKey options directly.

• credentialProvider (AWS.CredentialProviderChain) —

  the provider chain used to resolve credentials if no static credentials property is set.

• region (String) —

  the region to send service requests to. See AWS.TimestreamQuery.region for more information.

  the maximum amount of redirects to follow with a request. See AWS.TimestreamQuery.maxRedirects for more information.

• sslEnabled (Boolean) —

  whether to enable SSL for requests.

• paramValidation (Boolean|map) —

  whether input parameters should be validated against the operation description before sending the request. Defaults to true. Pass a map to enable any of the following specific validation features:

  • min [Boolean] — Validates that a value meets the min constraint. This is enabled by default when paramValidation is set to true.
  • max [Boolean] — Validates that a value meets the max constraint.
  • pattern [Boolean] — Validates that a string value matches a regular expression.
  • enum [Boolean] — Validates that a string value matches one of the allowable enum values.
• computeChecksums (Boolean) —

  whether to compute checksums for payload bodies when the service accepts it (currently supported in S3 only)

• convertResponseTypes (Boolean) —

  whether types are converted when parsing response data. Currently only supported for JSON based services. Turning this off may improve performance on large response payloads. Defaults to true.

• correctClockSkew (Boolean) —

  whether to apply a clock skew correction and retry requests that fail because of an skewed client clock. Defaults to false.

• s3ForcePathStyle (Boolean) —

  whether to force path style URLs for S3 objects.

• s3BucketEndpoint (Boolean) —

  whether the provided endpoint addresses an individual bucket (false if it addresses the root API endpoint). Note that setting this configuration option requires an endpoint to be provided explicitly to the service constructor.

• s3DisableBodySigning (Boolean) —

  whether S3 body signing should be disabled when using signature version v4. Body signing can only be disabled when using https. Defaults to true.

• s3UsEast1RegionalEndpoint ('legacy'|'regional') —

  whether to override the request region with the region inferred from requested resource's ARN. Only available for S3 buckets Defaults to true

• retryDelayOptions (map) —

  A set of options to configure the retry delay on retryable errors. Currently supported options are:

  • base [Integer] — The base number of milliseconds to use in the exponential backoff for operation retries. Defaults to 100 ms for all services except DynamoDB, where it defaults to 50ms.
  • customBackoff [function] — A custom function that accepts a retry count and error and returns the amount of time to delay in milliseconds. If the result is a non-zero negative value, no further retry attempts will be made. The base option will be ignored if this option is supplied. The function is only called for retryable errors.
• httpOptions (map) —

  A set of options to pass to the low-level HTTP request. Currently supported options are:

Property Details

endpoint ⇒ AWS.Endpoint (readwrite)

Returns an Endpoint object representing the endpoint URL for service requests.

Returns:

• (AWS.Endpoint) —

  an Endpoint object representing the endpoint URL for service requests.

Method Details

cancelQuery(params = {}, callback) ⇒ AWS.Request

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.

Service Reference:

• CancelQuery

Examples:

Calling the cancelQuery operation

var params = {
  QueryId: 'STRING_VALUE' /* required */
};
timestreamquery.cancelQuery(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

• params (Object) (defaults to: {}) —
  • QueryId — (String)

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

Callback (callback):

• function(err, data) { ... }

  Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

  Context (this):

  • (AWS.Response) —

    the response object containing error, data properties, and the original request object.

  Parameters:

  • err (Error) —

    the error object returned from the request. Set to null if the request is successful.

  • data (Object) —

    the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

    • CancellationMessage — (String)

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

Returns:

• (AWS.Request) —

  a handle to the operation request for subsequent event callback registration.

describeEndpoints(params = {}, callback) ⇒ AWS.Request

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.

Service Reference:

• DescribeEndpoints

Examples:

Calling the describeEndpoints operation

var params = {
};
timestreamquery.describeEndpoints(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

• params (Object) (defaults to: {})

Callback (callback):

• function(err, data) { ... }

  Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

  Context (this):

  • (AWS.Response) —

    the response object containing error, data properties, and the original request object.

  Parameters:

  • err (Error) —

    the error object returned from the request. Set to null if the request is successful.

  • data (Object) —

    the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

    • Endpoints — (Array<map>)

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

      • Address — required — (String)

        An endpoint address.

      • CachePeriodInMinutes — required — (Integer)

        The TTL for the endpoint, in minutes.

Returns:

• (AWS.Request) —

  a handle to the operation request for subsequent event callback registration.

query(params = {}, callback) ⇒ AWS.Request

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.

Service Reference:

• Query

Examples:

Calling the query operation

var params = {
  QueryString: 'STRING_VALUE', /* required */
  ClientToken: 'STRING_VALUE',
  MaxRows: 'NUMBER_VALUE',
  NextToken: 'STRING_VALUE'
};
timestreamquery.query(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

• params (Object) (defaults to: {}) —
  • QueryString — (String)

    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.

    If a token is not provided, the SDK will use a version 4 UUID.
  • 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.

Callback (callback):

• function(err, data) { ... }

  Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

  Context (this):

  • (AWS.Response) —

    the response object containing error, data properties, and the original request object.

  Parameters:

  • err (Error) —

    the error object returned from the request. Set to null if the request is successful.

  • data (Object) —

    the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

    • QueryId — (String)

      A unique ID for the given query.

    • NextToken — (String)

      A pagination token that can be used again on a Query call to get the next set of results.

    • Rows — (Array<map>)

      The result set rows returned by the query.

      • Data — required — (Array<map>)

        List of data points in a single row of the result set.
