operation

The type of operation to perform. You can specify the following values:

• 'INSERT' - Insert data as a new item into the DynamoDB table. This item uses the specified hash key as a partition key. If you specified a range key, the item uses the range key as a sort key.

• 'UPDATE' - Update an existing item of the DynamoDB table with new data. This item's partition key must match the specified hash key. If you specified a range key, the range key must match the item's sort key.

• 'DELETE' - Delete an existing item of the DynamoDB table. This item's partition key must match the specified hash key. If you specified a range key, the range key must match the item's sort key.

If you don't specify this parameter, AWS IoT Events triggers the 'INSERT' operation.
