massive-serve 0.1.11

A package for massive serving

Massive Serve User Guide

One command to download and serve a datastore---that's it 😎.

Installation

pip install massive-serve

Usage

To serve a demo datastore (30MB):

massive-serve serve --domain_name demo

To serve a wikipedia datastore (60GB):

massive-serve serve --domain_name dpr_wiki_contriever

More domains and retriever combinations coming soon!

It will then download and serve the index and print the API and one example request in the terminal, e.g.,

╔════════════════════════════════════════════════════════════╗
║                    MASSIVE SERVE SERVER                    ║
╠════════════════════════════════════════════════════════════╣
║ Domain: demo                                               ║
║ Server: XXX                                                ║
║ Port:   XXX                                                ║
║ Endpoint: XXX@XXX:XXX/search                               ║
╚════════════════════════════════════════════════════════════╝


Test your server with this curl command:

curl -X POST XXX@XXX:XXX/search -H "Content-Type: application/json" -d '{"query": "Tell me more about the stories of Einstein.", "n_docs": 1, "domains": "demo"}'

Send Requests

If the API has been served, you can either send single or bulk query requests to it.

Bash Examples.

# single-query request
curl -X POST <user>@<address>:<port>/search -H "Content-Type: application/json" -d '{"query": "Where was Marie Curie born?", "n_docs": 1, "domains": "dpr_wiki_contriever"}'

# multi-query request
curl -X POST <user>@<address>:<port>/search -H "Content-Type: application/json" -d '{"query": ["Where was Marie Curie born?", "What is the capital of France?", "Who invented the telephone?"], "n_docs": 2, "dpr_wiki_contriever": "MassiveDS"}'

Python Example.

import requests

json_data = {
    'query': 'Where was Marie Curie born?',
    "n_docs": 20,
    "domains": "dpr_wiki_contriever"
}
headers = {"Content-Type": "application/json"}

# Add 'http://' to the URL if it is not SSL/TLS secured, otherwise use 'https://'
response = requests.post('http://<user>@<address>:<port>/search', json=json_data, headers=headers)

print(response.status_code)
print(response.json())

Example output of a multi-query request:

Massive Serve Developer Guide

Environment Setup

Using Conda (Recommended for GPU support)

1. Create a new conda environment:

git clone https://github.com/RulinShao/massive-serve.git
cd massive-serve
conda env create -f conda-env.yml
conda activate massive-serve

To update the existing environment:

conda env update -n massive-serve -f conda-env.yml

Upload new index

python -m massive_serve.cli upload-data --domain_name demo

Test serving the index:

python -m massive_serve.cli serve --domain_name demo

Update package

Make sure the version in the setup.py has been updated to a different version. Then run:

rm -rf dist/ build/ massive_serve.egg-info/
pip install build twine
python -m build
python -m twine upload dist/*

Users can refresh their installed repo via:

pip install --upgrade massive-serve
