Config Overlays & Dotenv Expansion

Configure the plugin in getdotenv.config.json under plugins["aws/dynamodb"] (recommended). String values support $VAR and ${VAR:default} expansion from the composed dotenv context.

Example

{
  "plugins": {
    "aws/dynamodb": {
      "tablesPath": "./tables",
      "tokens": {
        "table": "table",
        "entityManager": "entityManager",
        "transform": "transform"
      },
      "generate": {
        "version": "001",
        "tableProperties": {
          "tableName": "$DDB_TABLE",
          "billingMode": "PAY_PER_REQUEST"
        }
      },
      "create": { "version": "001", "waiter": { "maxSeconds": 60 } },
      "delete": { "tableName": "$DDB_TABLE" },
      "purge": { "tableName": "$DDB_TABLE" },
      "migrate": {
        "sourceTable": "$SRC",
        "targetTable": "$TGT",
        "fromVersion": "001",
        "toVersion": "002",
        "pageSize": 100,
        "transformConcurrency": 2
      }
    }
  }
}
Copy

Managed table properties invariants

• If you set readCapacityUnits/writeCapacityUnits, you must also set billingMode: "PROVISIONED", and you must provide both RCU and WCU together.

Precedence

1. CLI flags (dotenv-expanded)
2. plugins["aws/dynamodb"] config (dotenv-expanded)
3. Documented defaults
