func GetDatasourceID

func GetDatasourceID(ctx context.Context) int64

Types

type AWSDatasource

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

AWSDatasource stores a cache of several instances. Each Map will depend on the datasource ID (and connection options):

• config: Base configuration. It will be used as base to populate datasource settings. It does not depend on connection options (only one per datasource)
• api: API instace with the common methods to contact the data source API.
• driver: Abstraction on top the upstream sql.Driver. Defined to handle multiple connections.
• db: Upstream database (sql.DB).
• sessionCache: AWS cache. This is not a Map since it does not depend on the datasource.

func New

func New() *AWSDatasource

func (*AWSDatasource) GetAPI

func (s *AWSDatasource) GetAPI(
	id int64,
	options sqlds.Options,
	settingsLoader models.Loader,
	apiLoader api.Loader,
) (api.AWSAPI, error)

GetAPI returns an API interface. When called multiple times with the same id and options, it will return a cached version of the API. The first time, it will use the loader functions to initialize the required settings and API.

func (*AWSDatasource) GetDB

func (s *AWSDatasource) GetDB(
	id int64,
	options sqlds.Options,
	settingsLoader models.Loader,
	apiLoader api.Loader,
	driverLoader driver.Loader,
) (*sql.DB, error)

GetDB returns a *sql.DB. It will use the loader functions to initialize the required settings, API and driver and finally create a DB.

func (*AWSDatasource) Init

func (s *AWSDatasource) Init(config backend.DataSourceInstanceSettings)

Init stores the data source configuration. It's needed for the GetDB and GetAPI functions
