Popoto - A Redis/Valkey ORM (Object-Relational Mapper)

Install

pip install popoto

Running

Popoto is a library, not a standalone service. It runs inside your application and talks to a Redis or Valkey server. To exercise it locally (and to run the test suite) you need a Redis/Valkey server listening on localhost:6379.

# 1. Start Redis (or Valkey), e.g. on macOS via Homebrew:
redis-server                     # or: brew services start redis

# 2. Install Popoto with dev dependencies:
uv venv && source .venv/bin/activate && uv pip install -e ".[dev]"

# 3. Run the test suite (auto-isolated on Redis DB 15):
pytest

By default Popoto connects to localhost:6379; set REDIS_URL to point at a different server. The pytest plugin isolates tests on Redis DB 15 (override with POPOTO_TEST_DB=<n>).

Basic Usage

from popoto import Model, KeyField, Field, SortedField

class Restaurant(Model):
    name = KeyField()
    cuisine = Field()
    rating = SortedField(type=float)

Restaurant.create(name="Burger Palace", cuisine="American", rating=4.5)

restaurant = Restaurant.query.get(name="Burger Palace")

print(f"{restaurant.name} serves {restaurant.cuisine} food.")
# => "Burger Palace serves American food."

Popoto Features

• very fast stores and queries
• familiar syntax, similar to Django models
• Async operations for asyncio-based applications
• Geometric distance search
• Timeseries for streaming data
• compatible with Pandas, Xarray for N-dimensional matrix search
• PubSub for message queues, streaming data processing
• Full Redis and Valkey support - works with both out of the box
• Agent Memory - programmable memory primitives for AI agents (decay, confidence, associations, context assembly)
• Content & Embeddings - large content storage, vector embeddings, and semantic search

Popoto is ideal for streaming data. The pub/sub module allows you to trigger state updates in real time. Currently being used in production for:

• trigger buy/sell actions from streaming price data
• robots sending each other messages for teamwork
• compressing sensor data and training neural networks

Advanced Usage

import popoto
from popoto import Relationship, DatetimeField

class Restaurant(popoto.Model):
    name = popoto.KeyField()
    cuisine = popoto.Field()
    rating = popoto.SortedField(type=float)
    location = popoto.GeoField()

class Order(popoto.Model):
    order_id = popoto.AutoKeyField()
    restaurant = Relationship(Restaurant)
    total = popoto.SortedField(type=float)
    status = popoto.Field(default="pending")
    created_at = DatetimeField(auto_now_add=True)

    class Meta:
        order_by = "-created_at"
        ttl = 2592000  # 30 days

Save Instances

restaurant = Restaurant(name="Burger Palace")
restaurant.cuisine = "American"
restaurant.rating = 4.5
restaurant.location = (40.7128, -74.0060)
restaurant.save()

order = Order.create(restaurant=restaurant, total=24.99)

Queries

from datetime import datetime, timedelta

midtown = (40.7549, -73.9840)
yesterday = datetime.now() - timedelta(days=1)

nearby_restaurants = Restaurant.query.filter(
    location=midtown,
    location_radius=5, location_radius_unit='km',
    rating__gte=4.0
)

print(len(nearby_restaurants))
# => 1

recent_orders = Order.query.filter(
    created_at__gte=yesterday,
    total__gte=10.00
)

Popoto gets its name from the Maui dolphin subspecies - the world's smallest dolphin subspecies. Because dolphins are fast moving, agile, and work together in social groups. In the same way, Popoto wraps Redis and Valkey to make it easy to manage streaming timeseries data and object persistence.
