EventSubscription

The EventSubscription resource allows you to manage AWS Neptune EventSubscriptions that notify you of specific database events. This capability is essential for monitoring and reacting to database changes effectively.

Minimal Example

Create a basic EventSubscription with essential properties and one optional property:

import AWS from "alchemy/aws/control";

const eventSubscription = await AWS.Neptune.EventSubscription("myEventSubscription", {
  SourceType: "db-instance",
  Enabled: true,
  EventCategories: ["availability", "configuration"],
  SnsTopicArn: "arn:aws:sns:us-west-2:123456789012:myTopic"
});

Advanced Configuration

Configure an EventSubscription with multiple source IDs and additional properties:

const advancedEventSubscription = await AWS.Neptune.EventSubscription("advancedEventSubscription", {
  SourceType: "db-cluster",
  Enabled: true,
  EventCategories: ["failure", "deletion"],
  SnsTopicArn: "arn:aws:sns:us-west-2:123456789012:myAdvancedTopic",
  SourceIds: ["my-db-cluster-1", "my-db-cluster-2"]
});

Adoption of Existing Resources

If you want to adopt an existing EventSubscription instead of failing when it already exists, you can set the adopt property:

const adoptExistingSubscription = await AWS.Neptune.EventSubscription("existingEventSubscription", {
  SourceType: "db-instance",
  Enabled: true,
  EventCategories: ["creation", "modification"],
  SnsTopicArn: "arn:aws:sns:us-west-2:123456789012:myAdoptedTopic",
  adopt: true
});

Multi-Category Notification

Set up an EventSubscription that monitors multiple event categories for a specific source:

const multiCategorySubscription = await AWS.Neptune.EventSubscription("multiCategorySubscription", {
  SourceType: "db-instance",
  Enabled: true,
  EventCategories: ["availability", "configuration", "deletion"],
  SnsTopicArn: "arn:aws:sns:us-west-2:123456789012:multiCategoryTopic",
  SourceIds: ["my-db-instance-1"]
});
