Functions ¶
func CreateChunkEmbeddingsTableSQL ¶ added in v0.2.0
CreateChunkEmbeddingsTableSQL generates the embeddings table with dynamic dimensions
func GetEmbeddingDimensions ¶ added in v0.2.0
GetEmbeddingDimensions retrieves stored embedding dimensions, returns 0 if not set
func IsWALEnabled ¶
IsWALEnabled checks if WAL mode is enabled for the database.
func MigrateEmbeddingDimensions ¶ added in v0.2.0
MigrateEmbeddingDimensions drops and recreates the embeddings table with new dimensions. This is required when changing embedding models with different vector sizes. All existing embeddings will be lost and repos will need to be re-embedded.
func Open ¶
Open opens (or creates) the SQLite database at the given path, applies all pragmas, loads the sqlite-vec extension, and runs schema migrations. The caller is responsible for calling Close(). embeddingDimensions specifies the vector size for embeddings (e.g., 768 for Gemini).
func RunMigrations ¶
RunMigrations runs all schema migrations with the specified embedding dimensions. Each statement is idempotent (IF NOT EXISTS) so running migrations multiple times is safe. If the embedding dimensions change from what's stored, a migration is required.
func SetEmbeddingDimensions ¶ added in v0.2.0
SetEmbeddingDimensions stores the embedding dimensions
