Types

type KeyValue

type KeyValue struct {
	Key      string    `db:"key"`
	Value    []byte    `db:"value"`
	Inserted time.Time `db:"inserted"`
}

type PGKeyValueStore

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

PGKeyValueStore is a time-limited key-value store backed by postgres with a local LRU cache. The store is write-only, i.e., writing to an existing key will return an error (of type *armadaerrors.ErrAlreadyExists). Keys can only be deleted by running the cleanup function. Deleting keys does not cause caches to update, i.e., nodes may have an inconsistent view if keys are deleted.
