A 10x faster, cheaper, and better vector database
Documentation • Discord • Twitter • Blog • Feedback
Epsilla is an open-source vector database. Our focus is on ensuring scalability, high performance, and cost-effectiveness of vector search. EpsillaDB bridges the gap between information retrieval and memory retention in Large Language Models.
The key features of Epsilla include:
-
High performance and production-scale similarity search for embedding vectors.
-
Full fledged database management system with familiar database, table, and field concepts. Vector is just another field type.
-
Native Python support and REST API interface.
Epsilla's core is written in C++ and leverages the advanced academic parallel graph traversal techniques for vector indexing, achieving 10 times faster vector search than HNSW while maintaining precision levels of over 99.9%.
1. Run Backend in Docker
docker pull epsilla/vectordb
docker run --pull=always -d -p 8888:8888 -v /tmp:/tmp epsilla/vectordb2. Interact with Python Client
pip install pyepsillafrom pyepsilla import vectordb
client = vectordb.Client(host='localhost', port='8888')
client.load_db(db_name="MyDB", db_path="/tmp/epsilla")
client.use_db(db_name="MyDB")
client.create_table(
table_name="MyTable",
table_fields=[
{"name": "ID", "dataType": "INT"},
{"name": "Doc", "dataType": "STRING"},
{"name": "Embedding", "dataType": "VECTOR_FLOAT", "dimensions": 4}
]
)
client.insert(
table_name="MyTable",
records=[
{"ID": 1, "Doc": "Berlin", "Embedding": [0.05, 0.61, 0.76, 0.74]},
{"ID": 2, "Doc": "London", "Embedding": [0.19, 0.81, 0.75, 0.11]},

1. Build Epsilla Python Bindings lib package
cd engine
bash build.sh
ls -lh build/*.so2. Run test with python bindings lib "epsilla.so" "libvectordb_dylib.so in the folder "build" built in the previous step
cd engine
export PYTHONPATH=./build/
export DB_PATH=/tmp/db33
