DomainProps has an 'advancedOptions' field [code] [doc]:

  /**
   * Additional options to specify for the Amazon ES domain.
   *
   * @default - no advanced options are specified
   */
  readonly advancedOptions?: { [key: string]: (string) };

However, this field doesn't seem to be used anywhere. [code search]

In particular, it's not used to set the 'AdvancedOptions' field in CloudFormation's AWS::Elasticsearch::Domain resource [doc], which was surely the intent.

Reproduction Steps

• Take any CDK code that uses the 'Domain' class to create an Elasticsearch domain.
• Add the 'advancedOptions' field, which is a map from string keys to string values, containing whatever mappings strike your fancy.
  • The "Advanced Options" section at https://docs.aws.amazon.com/elasticsearch-service/latest/developerguide/es-createupdatedomains.html#es-createdomain-configure-advanced-options lists the ones that Amazon Elasticsearch Service currently supports, though I think that other mappings might still be accepted as no-ops.
• Execute the CDK code to obtain the generated CloudFormation template.
• [optional] Deploy the CloudFormation template to create the actual Elasticsearch domain.

What did you expect to happen?

• The generated CloudFormation template should include an 'AdvancedOptions' field with the specified mappings.
• The resultant Elasticsearch domain should have the specified advanced options.

What actually happened?

• The generated CloudFormation template does not have an 'AdvancedOptions' field, and more generally, the 'advancedOptions' field seems to have no effect on the generated CloudFormation template. (I confirmed this via diff -r.)
• The resultant Elasticsearch domain does not have the specified advanced options, and more generally, the 'advancedOptions' field has no effect on the resultant Elasticsearch domain.

Environment

• cdk 1.96.0
• TypeScript ~4.0.5
