Class SqliteSemanticMemory
- Namespace
- IntentSharp.Memory
- Assembly
- IntentSharp.dll
SQLite-backed memory that survives restarts. Embeddings are stored as little-endian float32 blobs.
Recall ranks the most recent RecallCandidateLimit entries in process. A failed embedding is logged at
Warning and the entry is kept without one; only the caller's cancellation propagates.

Constructors
- SqliteSemanticMemory(string, IAIProvider?, ILogger?)
Opens the database file, creating the file and its table when they are missing. Without an embedding provider, or with one that does not support embeddings, recall uses word overlap only.
Properties
- RecallCandidateLimit
How many of the most recent entries recall considers. Older entries are kept but never recalled. Default 2000.
Methods
- ClearAsync(CancellationToken)
Deletes every entry from the database file. The file and its table stay.
- GetStatsAsync(CancellationToken)
Returns counts over every stored entry.
- RecallAsync(string, int, CancellationToken)
Returns up to
maxResultsof the most recent RecallCandidateLimit entries, most similar toqueryfirst and newer first among equal scores. Uses embedding similarity for entries that have an embedding when the query can be embedded, and word overlap otherwise; entries with no similarity are left out.
- RecordAsync(MemoryEntry, CancellationToken)
Writes the entry to the database, first embedding its intent when an embedding provider is set and the entry has no embedding.
