Configuration
4 fields, none required. A dotted path is a nested object and name[] an array of objects — the editor renders the same tree.
| Field | Type | Required | Default | Constraints | Example |
|---|---|---|---|---|---|
region AWS region (overrides the connection). | string | No | — | — | — |
cluster_id One cluster (optional). | string | No | — | — | — |
max_records Max clusters (20-100). | number | No | — | ≥ 1 | — |
next_token Continue from a previous run of this node by passing that run's next_token output; leave blank for the first page. | string | No | — | — | — |
Output
One shape.

| Field | Type | Example |
|---|---|---|
clusters One entry per cluster: 'cluster_id', 'status', 'engine', 'engine_version', 'node_type', 'endpoint' and 'endpoint_port', plus the identifiers a later step needs to act on it — 'arn' (what the tagging APIs take), 'replication_group_id' (empty unless the cluster is a member of one), 'cache_subnet_group_name' and 'preferred_outpost_arn'. | array | — |
count | number | — |
next_token Token for the next page; empty when there are no further pages. | string | — |

In a technical demo we add the Amazon ElastiCache connection, drop the node on the canvas and let Workflow Health pre-flight it before the first real run.
