DBProxyTargetGroup

Source: src/AWS/RDS/DBProxyTargetGroup.ts

The proxy target group that registers Aurora clusters or instances behind an RDS Proxy.

Every DBProxy has exactly one default target group; this resource adopts it, tunes its connection pool, and reconciles the registered cluster/instance targets. Deleting it deregisters the targets rather than deleting the group itself.

Registering Targets

Register a Cluster Behind a Proxy

const targets = yield* DBProxyTargetGroup("ProxyTargets", {
  dbProxyName: proxy.dbProxyName,
  dbClusterIdentifiers: [cluster.dbClusterIdentifier],
});

Tune the Connection Pool

const targets = yield* DBProxyTargetGroup("ProxyTargets", {
  dbProxyName: proxy.dbProxyName,
  dbClusterIdentifiers: [cluster.dbClusterIdentifier],
  connectionPoolConfig: {
    MaxConnectionsPercent: 90,
    MaxIdleConnectionsPercent: 10,
  },
});
