store Expiration, Vectors, and Types
Last updated
This page lists the core/store expiration and vector methods and the exported Entry, ValueType, and AOFRecord types.
Expiration
func (c *core) TTL(key string) int64
func (c *core) Expire(key string, seconds int64) error
func (c *core) ExpireAt(key string, timestamp int64) error
func (c *core) Persist(key string) error
TTL returns -2 when missing or expired and -1 without expiry.
Vectors
var ErrNoEmbedder = errors.New("no embedder: OPENAI_API_KEY not provided")
func (c *core) VSearch(ctx context.Context, text, pattern string, k int) ([]string, error)
func (c *core) VSim(key1, key2 string) (float64, error)
func (c *core) VGet(key string) ([]float32, bool)
