Inputs

Input	Description
awsAccessKeyID	Your AWS Access Key (only needed if you don't give your Lambda function rights to interact with Amazon DyanmoDB)
awsSecretAccessKey	Your AWS Secret Key (only needed if you don't give your Lambda function rights to interact with Amazon DyanmoDB)
awsRegion	The AWS region you're running DynamoDB in
dynamoDBTableName	The name of your DynamoDB table
dynamoDBKeyConditionExpression	The expression to search for (for example Artist = :name to search for results where the key Artist has the value of :name)
dynamoDBExpressionAttributes	A JSON array representation of your expression attributes (using the example above that would be [{"Name":":name", "Value":"Leon"}] to search where the Artist is called Leon)
dynamoDBFilterExpression	The filter expression you want to apply on the result set before it is sent back to activity

Ouputs

Output	Description
result	The JSON representation of the result of your query
scannedCount	The number of items evaluated
consumedCapacity	The number of capacity units used by the query

• func NewActivity(metadata *activity.Metadata) activity.Activity
• type ExpressionAttribute
• type MyActivity
  • func (a *MyActivity) Eval(context activity.Context) (done bool, err error)
  • func (a *MyActivity) Metadata() *activity.Metadata

Functions

func NewActivity

func NewActivity(metadata *activity.Metadata) activity.Activity

NewActivity creates a new activity

Types

type ExpressionAttribute

type ExpressionAttribute struct {
	Name  string
	Value string
}

ExpressionAttribute is a structure representing the JSON payload for the expression syntax

type MyActivity

type MyActivity struct {
	// contains filtered or unexported fields
}

MyActivity is a stub for your Activity implementation

func (*MyActivity) Eval

func (a *MyActivity) Eval(context activity.Context) (done bool, err error)

Eval implements activity.Activity.Eval

func (*MyActivity) Metadata

func (a *MyActivity) Metadata() *activity.Metadata

Metadata implements activity.Activity.Metadata
