Functions

func BuildScanFilterAttr

func BuildScanFilterAttr(objPtr runtime.Object, p storage.SelectionPredicate) (filterExpression string, expressionAttributeNames map[string]*string, expressionAttributeValues map[string]*awsdb.AttributeValue)

func BuildUpdateAttr

func BuildUpdateAttr(newObj runtime.Object, oldObj runtime.Object, attr map[string]interface{}) (updateExpression string, expressionAttributeNames map[string]*string, expressionAttributeValues map[string]*awsdb.AttributeValue, err error)

BuildUpdateAttr input attr like as:

type nested Struct{
	key1 string
	key2 string
}

type Test Struct{
	key1 string `json:"key1,omitempty"`
	key2 string
	nested nested `json:"nested,omitempty"`
}

if you want update Test.key1 and nested.key1 will be have map:

attr:=map[string]interface{}{
	"key1":value1,
	"nested.#key1":value2,
}

func ConvertByteToMap

func ConvertByteToMap(data []byte) (map[string]interface{}, error)

func ConvertTOJson

func ConvertTOJson(items *[]map[string]*awsdb.AttributeValue) ([]map[string]interface{}, int64, error)

func CreateTable

func CreateTable(dbHandler *awsdb.DynamoDB, table string) (string, error)

func New

func New(sess *session.Session, table string, codec runtime.Codec) *store

New create a mongo store

func RandStringRunes

func RandStringRunes(n int) string

func ScanFilterWithFileds

func ScanFilterWithFileds(p storage.SelectionPredicate,
	expressionAttributeNames map[string]*string,
	expressionAttributeValues map[string]*awsdb.AttributeValue) (expression []string)

ScanFilterWithFileds range FieldSelector convert into dynamodb scan return string is a slice constain of filter expression for dynamodb

func ScanFilterWithLables

func ScanFilterWithLables(p storage.SelectionPredicate,
	expressionAttributeNames map[string]*string,
	expressionAttributeValues map[string]*awsdb.AttributeValue) (expression []string)

ScanFilterWithFileds range LablesSelector convert into dynamodb scan return string is a slice constain of filter expression for dynamodb
