Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

Amazon RDS provides an HTTP endpoint to run SQL statements on an Amazon Aurora Serverless DB cluster. To run these statements, you work with the Data Service API.

For more information about the Data Service API, see Using the Data API for Aurora Serverless in the Amazon Aurora User Guide.

Note: If you have questions or comments related to the Data API, send email to Rds-data-api-feedback@amazon.com.

Sending a Request Using RDSDataService

var rdsdataservice = new AWS.RDSDataService();
rdsdataservice.batchExecuteStatement(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the RDSDataService object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var rdsdataservice = new AWS.RDSDataService({apiVersion: '2018-08-01'});

You can also set the API version globally in AWS.config.apiVersions using the rdsdataservice service identifier:

AWS.config.apiVersions = {
  rdsdataservice: '2018-08-01',
  // other service API versions
};

var rdsdataservice = new AWS.RDSDataService();

Constructor Details

new AWS.RDSDataService(options = {}) ⇒ Object

Constructs a service object. This object has one method for each API operation.

Examples:

Constructing a RDSDataService object

var rdsdataservice = new AWS.RDSDataService({apiVersion: '2018-08-01'});

Options Hash (options):

  • params (map)

    An optional map of parameters to bind to every request sent by this service object. For more information on bound parameters, see "Working with Services" in the Getting Started Guide.

  • endpoint (String)

    The endpoint URI to send requests to. The default endpoint is built from the configured region. The endpoint should be a string like 'https://{service}.{region}.amazonaws.com'.

  • accessKeyId (String)

    your AWS access key ID.

  • secretAccessKey (String)

    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.RDSDataService.region for more information.

  • maxRetries (Integer)

    the maximum amount of retries to attempt with a request. See AWS.RDSDataService.maxRetries for more information.

  • maxRedirects (Integer)

    the maximum amount of redirects to follow with a request. See AWS.RDSDataService.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.

  • 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.
  • httpOptions (map)

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

    • proxy [String] — the URL to proxy requests through
    • agent [http.Agent, https.Agent] — the Agent object to perform HTTP requests with. Used for connection pooling. Defaults to the global agent (http.globalAgent) for non-SSL connections. Note that for SSL connections, a special Agent object is used in order to enable peer certificate verification. This feature is only available in the Node.js environment.
    • connectTimeout [Integer] — Sets the socket to timeout after failing to establish a connection with the server after connectTimeout milliseconds. This timeout has no effect once a socket connection has been established.
    • timeout [Integer] — Sets the socket to timeout after timeout milliseconds of inactivity on the socket. Defaults to two minutes (120000).
    • xhrAsync [Boolean] — Whether the SDK will send asynchronous HTTP requests. Used in the browser environment only. Set to false to send requests synchronously. Defaults to true (async on).
    • xhrWithCredentials [Boolean] — Sets the "withCredentials" property of an XMLHttpRequest object. Used in the browser environment only. Defaults to false.
  • apiVersion (String, Date)

    a String in YYYY-MM-DD format (or a date) that represents the latest possible API version that can be used in all services (unless overridden by apiVersions). Specify 'latest' to use the latest possible version.

  • apiVersions (map<String, String|Date>)

    a map of service identifiers (the lowercase service class name) with the API version to use when instantiating a service. Specify 'latest' for each individual that can use the latest available version.

  • logger (#write, #log)

    an object that responds to .write() (like a stream) or .log() (like the console object) in order to log information about requests

  • systemClockOffset (Number)

    an offset value in milliseconds to apply to all signing times. Use this to compensate for clock skew when your system may be out of sync with the service time. Note that this configuration option can only be applied to the global AWS.config object and cannot be overridden in service-specific configuration. Defaults to 0 milliseconds.

  • signatureVersion (String)

    the signature version to sign requests with (overriding the API configuration). Possible values are: 'v2', 'v3', 'v4'.

  • signatureCache (Boolean)

    whether the signature to sign requests with (overriding the API configuration) is cached. Only applies to the signature version 'v4'. Defaults to true.

Method Details

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

Runs a batch SQL statement over an array of data.

You can run bulk update and insert operations for multiple records using a DML statement with different parameter sets. Bulk operations can provide a significant performance improvement over individual insert and update operations.

If a call isn't part of a transaction because it doesn't include the transactionID parameter, changes that result from the call are committed automatically.

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

Runs a SQL statement against a database.

If a call isn't part of a transaction because it doesn't include the transactionID parameter, changes that result from the call are committed automatically.

The response size limit is 1 MB or 1,000 records. If the call returns more than 1 MB of response data or over 1,000 records, the call is terminated.

Service Reference:

Examples:

    {
      name: 'STRING_VALUE',
      value: {
        arrayValue: { /* ArrayValue */
          arrayValues: [
            /* recursive ArrayValue */,
            /* more items */

        isNull: true || false,
        longValue: 'NUMBER_VALUE',
        stringValue: 'STRING_VALUE'
      }
    },
    /* more items */
  ],
  resultSetOptions: {
    decimalReturnType: DOUBLE_OR_LONG | STRING
  },
  schema: 'STRING_VALUE',
  transactionId: 'STRING_VALUE'
};
rdsdataservice.executeStatement(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: {})
    • continueAfterTimeout — (Boolean)

      A value that indicates whether to continue running the statement after the call times out. By default, the statement stops running when the call times out.

      For DDL statements, we recommend continuing to run the statement after the call times out. When a DDL statement terminates before it is finished running, it can result in errors and possibly corrupted data structures.

    • database — (String)
