Patchvec — A lightweight, pluggable vector search microservice.

PatchVec — A lightweight, pluggable vector search microservice.

Upload → chunk → index (with metadata) → search via REST and CLI.

Highlights

• Multi-tenant collections: /collections/{tenant}/{name}
• Upload and search TXT, CSV, and PDF
• Deterministic provenance: every hit returns doc id, page, offset, snippet
• Metadata filters on search ({"filters": {"docid": "DOC-1"}})
• REST and CLI entry points
• Health/metrics endpoints + Prometheus exporter
• Pluggable embeddings and stores; default backend is local

Requirements

• Python 3.10–3.14

Install (PyPI)

python -m venv .venv
source .venv/bin/activate
pip install patchvec

CPU-only deployments can use the PyTorch CPU wheel index:

pip install "patchvec[cpu]" \
  --index-url https://download.pytorch.org/whl/cpu \
  --extra-index-url https://pypi.org/simple

Quickstart

# Start the server (installed entry point)
pavesrv

# Or run with uvicorn manually if you prefer:
uvicorn pave.main:app --host 0.0.0.0 --port 8086

Auth defaults to none only for dev. For production, set static auth:

export PATCHVEC_AUTH__MODE=static
export PATCHVEC_AUTH__GLOBAL_KEY="your-secret"

Minimal config (optional)

By default PatchVec runs with sensible local defaults. To customize, create config.yml:

vector_store:
  type: default
embedder:
  type: default
auth:
  mode: static
  global_key: ${PATCHVEC_GLOBAL_KEY}

Then export:

export PATCHVEC_CONFIG=./config.yml
export PATCHVEC_GLOBAL_KEY="your-secret"

CLI example

pavecli create-collection demo books
pavecli upload demo books demo/20k_leagues.txt --docid=verne-20k --metadata='{"lang":"en"}'
pavecli search demo books "captain nemo" -k 5

REST example

# Create a collection
curl -X POST http://localhost:8086/collections/demo/books \
  -H "Authorization: Bearer your-secret"

# Upload a TXT document
curl -X POST http://localhost:8086/collections/demo/books/documents \
  -H "Authorization: Bearer your-secret" \
  -F "file=@demo/20k_leagues.txt" -F "docid=verne-20k" \
  -F 'metadata={"lang":"en"}'

# Search (GET, no filters)
curl -G --data-urlencode "q=hello" \
  -H "Authorization: Bearer your-secret" \
  http://localhost:8086/collections/demo/books/search

# Search (POST, with filters)
curl -X POST http://localhost:8086/collections/demo/books/search \
  -H "Authorization: Bearer your-secret" \
  -H "Content-Type: application/json" \
  -d '{"q":"captain nemo","k":5,"filters":{"docid":"verne-20k"}}'
