Cached Sentence Transformer
PostgreSQL-backed embedding cache for SentenceTransformers.
This package provides a small wrapper that caches computed sentence embeddings in a Postgres
table keyed by a stable hash of (model, normalize flag, text), so repeated runs can reuse
stored vectors instead of recomputing them.
Installation
pip install cached-sentence-transformer
Quickstart
from cached_sentence_transformer import CachedSentenceTransformer
st = CachedSentenceTransformer(
model_name_or_path="sentence-transformers/all-MiniLM-L6-v2",
pg_dsn="host=localhost port=5432 dbname=mydb user=myuser password=mypassword",
)
emb = st.encode(["hello", "world"], normalize_embeddings=True)
st.close()
Environment-based DSN
If you do not pass pg_dsn, the wrapper will attempt to build it from environment variables
(auto loads environment variables in the .env file in the current working directory) and
will fail fast if any are missing:
