Types ¶
type Store ¶
type Store struct {
// contains filtered or unexported fields
}
Store represents access to the postgres database for beacon management.
func NewStore ¶
NewStore returns a new store that provides the CRUD based API needed for supporting drand serialization.
func (*Store) AddBeaconID ¶
AddBeaconID adds the beacon to the database if it does not exist.
func (*Store) AddFK ¶
AddFK reconstructs the relation between beacons and beacon_details tables after Store.DropFK was called.
func (*Store) BatchPut ¶
BatchPut is useful if you want to write a lot of beacons to the database at once.
func (*Store) DropFK ¶
DropFK is used to optimize the calls to Store.BatchPut and should be called before it. It drops the relation between beacons and beacon_details tables.
