DBClusterEndpoint

Source: src/AWS/RDS/DBClusterEndpoint.ts

A custom Aurora cluster endpoint — a DNS name that routes to a chosen subset of a cluster’s instances, on top of the built-in writer and reader endpoints of a DBCluster.

Use it to pin analytics traffic to specific readers or to keep a stable address across instance replacements. Changing the identifier or owning cluster replaces the endpoint; type and membership update in place.

Creating Custom Endpoints

Reader Endpoint for a Cluster

const readers = yield* DBClusterEndpoint("Readers", {
  dbClusterIdentifier: cluster.dbClusterIdentifier,
  endpointType: "READER",
});

Pin Specific Instances

const analytics = yield* DBClusterEndpoint("Analytics", {
  dbClusterIdentifier: cluster.dbClusterIdentifier,
  endpointType: "ANY",
  staticMembers: [reporting.dbInstanceIdentifier],
});
