node-red-contrib-dynamodb-scan

Wrap aws sdk dynamo db scan functionality.

Usage

Input

Payload input expects key, reservedKey, value and operator. Reserved keys such as year or name need to be substitued with a key that isn't reserved.

{
    key: "nme",
    reservedKey: "name",
    value: true,
    operator: "="
}

Output

Response from asw-sdk passed directly to msg.payload.

  • Items - response array.
  • Count - number of items returned
  • Scanned Count - number of items scanned.

Example

{
    "Items": [
        { 
            "name": "John"
        }
    ],
    "Count": 1,
    "ScannedCount": 4
}

Todo

  • Multiple scan parameters
  • Default to key if reserved key isn't present or could even accept just key and always provide a substition for the reserved key. i.e. pass in name and substitue with name_reserved_key.
