Types ¶
type Store ¶
type Store struct {
// contains filtered or unexported fields
}
Store is a sqlite-vec backed store.Store.
func Open ¶
Open opens (creating if needed) the sqlite database at path and ensures the schema exists for the given embedding dimensionality.
func (*Store) DeleteIfExpiredBefore ¶
func (s *Store) DeleteIfExpiredBefore(ctx context.Context, namespace, id string, cutoff time.Time) error
DeleteIfExpiredBefore removes a memory only if its expiry is still at or before cutoff. Returns ErrNotFound when the memory is absent or its TTL was slid past cutoff by Reinforce since the last ListExpired call.
func (*Store) DeleteNamespace ¶ added in v0.0.8
DeleteNamespace removes every memory in a namespace, including vector and FTS index entries. Returns the number of memories deleted.
func (*Store) GetByFingerprint ¶ added in v0.2.9
func (s *Store) GetByFingerprint( ctx context.Context, namespace string, tier memory.Tier, fingerprint string, now time.Time, ) (*memory.Memory, error)
GetByFingerprint returns the most recent live memory in namespace+tier whose content fingerprint matches. Superseded and expired rows are excluded so a dead duplicate never absorbs a fresh write.
func (*Store) KeywordSearch ¶
func (s *Store) KeywordSearch(ctx context.Context, namespace, query string, f store.Filter, k int) ([]store.Scored, error)
KeywordSearch returns the k best BM25 full-text matches in the namespace.
func (*Store) List ¶
func (s *Store) List(ctx context.Context, namespace string, f store.Filter, limit int) ([]*memory.Memory, error)
List returns memories in a namespace matching f (without embeddings).
func (*Store) ListExpired ¶
func (s *Store) ListExpired(ctx context.Context, now time.Time, limit int) ([]*memory.Memory, error)
ListExpired returns up to limit memories whose TTL has passed.
func (*Store) ListNamespaces ¶
ListNamespaces returns the distinct namespaces holding memories.
func (*Store) Reassign ¶ added in v0.0.11
func (s *Store) Reassign(ctx context.Context, fromNS string, ids []string, toNS string) (int64, error)
Reassign moves memories from fromNS to toNS, updating the namespace column and rewriting the vec0 partition row (the FTS row carries no namespace). IDs absent from fromNS are skipped; IDs are globally unique so a move never collides in toNS.
func (*Store) Reinforce ¶
func (s *Store) Reinforce(ctx context.Context, namespace string, ids []string, accessedAt time.Time, newExpiry *time.Time) error
Reinforce bumps access_count/last_accessed_at and optionally slides the TTL.
func (*Store) Retier ¶ added in v0.0.11
func (s *Store) Retier(ctx context.Context, namespace, id string, tier memory.Tier, expiresAt *time.Time) error
Retier changes a memory's tier and expiry in place. Tier and expiry live only in the memories row, so no vector/FTS reindex is required.
func (*Store) SetConfidence ¶ added in v0.0.11
func (s *Store) SetConfidence(ctx context.Context, namespace, id string, confidence float64, now time.Time) error
SetConfidence updates a memory's confidence and bumps updated_at to now. Confidence lives only in the memories row, so no vector/FTS reindex is needed.
func (*Store) SetMetrics ¶
SetMetrics installs an observability sink. Passing nil disables metrics.
func (*Store) SetSuperseded ¶
SetSuperseded records that a memory was replaced by supersededBy.
