Example

scanItems is an example how to use Amazon DynamoDB's Scan API operation with the SDK's dynamodbattributes.UnmarshalListOfMaps to unmarshal the Scan response's Items []map[string]*dynamodb.AttributeValue field. This unmarshaler can be used with all []map[string]*dynamodb.AttributeValue type fields.

Go Type

The Item time will be used by the example to unmarshal the DynamoDB table's items to.

type Item struct {
	Key  int
	Desc string
	Data map[string]interface{}
}

Use Go tags to define what the name is of the attribute in your DynamoDB table. See AWS SDK for Go API Reference: Marshal for more information.

In DynamoDB the structure of the item to be returned will be:

{
  "Data": {
    "Value 1": "abc",
    "Value 2": 1234567890
  },
  "Desc": "First ddb item",
  "Key": 1
}

Usage

go run -tags example scanItems.go -table "<table_name>" -region "<optional_region>"

Output

0: Key: 123, Desc: An item in the DynamoDB table
	Num Data Values: 0
1: Key: 2, Desc: Second ddb item
	Num Data Values: 2
	- "A Field": 123
	- "Another Field": abc
2: Key: 1, Desc: First ddb item
	Num Data Values: 2
	- "Value 1": abc
	- "Value 2": 1234567890
