caching

caching library used by connectors

How it works :

connector should check if IsKeyCreated if key is not already created, connector should CreateCache.

Caching has 2 functionalities:

1- IsKeyCreated it takes objectID which check if the provided key is already cached, key is a full path for connectors it is cache/{connectorName}/{objectID}

2- CreateCache which store a cache record, it takes []map[string]interface each map contain 2 keys id and data.id is the objectID. data is the bytes of the actual object.

3- GetLastSync which get connector last sync date

4- SetLastSync which update connector last sync date

Types

type Manager

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

func NewManager

func NewManager(connector string, environment string) *Manager

func (*Manager) Create

func (m *Manager) Create(endpoint string, data []map[string]interface{}) error

Create new cache record

func (*Manager) GetFileByKey

func (m *Manager) GetFileByKey(endpoint string, id string) ([]byte, error)

GetFileByKey get file by key

func (*Manager) GetLastSync

func (m *Manager) GetLastSync(endpoint string) (time.Time, error)

GetLastSync get connector sync date, if it is not exist return epoch date

func (*Manager) IsKeyCreated

func (m *Manager) IsKeyCreated(endpoint string, id string) (bool, error)

IsKeyCreated check if the key already exists

func (*Manager) SetLastSync

func (m *Manager) SetLastSync(endpoint string, lastSync time.Time) error

SetLastSync update connector last sync date

func (*Manager) UpdateFileByKey

func (m *Manager) UpdateFileByKey(endpoint string, id string, data []byte) error

UpdateFileByKey get file by key

type S3Manager

type S3Manager interface {
	Save(payload []byte) error
	SaveWithKey(payload []byte, key string) error
	GetKeys() ([]string, error)
	Get(key string) ([]byte, error)
	Delete(key string) error
}
