Function hashKey

app/controlplane/pkg/data/lock.go:97–101

hashKey turns an opaque string key into the int64 that pg_advisory_lock expects. FNV-1a gives a stable, well-distributed mapping with effectively no collision risk for the handful of named locks this package uses.

(key string)

// mapping with effectively no collision risk for the handful of named
// locks this package uses.
func hashKey(key string) int64 {
	h := fnv.New64a()
	_, _ = h.Write([]byte(key))
	return int64(h.Sum64()) //nolint:gosec // intentional wraparound; pg accepts any int64
