Functions

func InitAll 

func InitAll(metrics module.CacheMetrics, db *badger.DB) *storage.All

func InitPublic 

func InitPublic(opts badger.Options) (*badger.DB, error)

InitPublic initializes a public database by checking and setting the database type marker. If an existing, inconsistent type marker is set, this method will return an error. Once a database type marker has been set using these methods, the type cannot be changed.

func InitSecret 

func InitSecret(opts badger.Options) (*badger.DB, error)

InitSecret initializes a secrets database by checking and setting the database type marker. If an existing, inconsistent type marker is set, this method will return an error. Once a database type marker has been set using these methods, the type cannot be changed.

func (*ServiceEvents) BatchRemoveByBlockID 

func (e *ServiceEvents) BatchRemoveByBlockID(blockID flow.Identifier, batch storage.BatchStorage) error

BatchRemoveByBlockID removes service events keyed by a blockID in provided batch No errors are expected during normal operation, even if no entries are matched. If Badger unexpectedly fails to process the request, the error is wrapped in a generic error and returned.

func (*ServiceEvents) BatchStore 

func (e *ServiceEvents) BatchStore(blockID flow.Identifier, events []flow.Event, batch storage.BatchStorage) error

BatchStore stores service events keyed by a blockID in provided batch No errors are expected during normal operation, even if no entries are matched. If Badger unexpectedly fails to process the request, the error is wrapped in a generic error and returned.

func (*ServiceEvents) ByBlockID 

func (e *ServiceEvents) ByBlockID(blockID flow.Identifier) ([]flow.Event, error)

ByBlockID returns the events for the given block ID

func (*ServiceEvents) RemoveByBlockID 

func (e *ServiceEvents) RemoveByBlockID(blockID flow.Identifier) error

RemoveByBlockID removes service events by block ID
