Redis

Redis for state and caching

Redis

Redis is used for state management, caching, and vector search.

Installation

pip install "praisonaiagents[tools]"

Docker Setup

docker run -d --name praison-redis -p 6379:6379 redis:7

Quick Start

from praisonaiagents import Agent

agent = Agent(
    name="Assistant",
    instructions="You are a helpful assistant.",
    memory={
        "backend": "redis",
        "db": "redis://localhost:6379",
        "session_id": "my-session"
    }
)

response = agent.start("Hello!")
print(response)

Connection String Format

redis://localhost:6379
redis://:password@host:port/db_number

Environment Variables

export PRAISON_STATE_URL="redis://localhost:6379"

import os
from praisonaiagents import Agent

agent = Agent(
    name="Assistant",
    memory={"db": os.getenv("PRAISON_STATE_URL")}
)

CLI

# Validate connection
praisonai persistence doctor \
    --state-url "redis://localhost:6379"

Use Cases

• Session state caching
• Rate limiting
• Temporary data storage
• Vector search (Redis Stack)

When to Use

✅ Good for:

• Session caching
• Rate limiting
• Real-time features
• Pub/sub messaging

❌ Not recommended for:

• Long-term storage
• Complex queries
• Large datasets

Storage Backend (Advanced)

For training data, sessions, and general persistence, use the RedisBackend:

BaseJSONStore

from praisonaiagents.storage import RedisBackend, BaseJSONStore

backend = RedisBackend(
    url="redis://localhost:6379",
    prefix="praison:",
    ttl=3600  # 1 hour TTL
)
store = BaseJSONStore("session.json", backend=backend)
store.save({"messages": ["Hello"]})
data = store.load()

CLI Usage

# Training with Redis backend
praisonai train agents --input "Hello" --storage-backend redis://localhost:6379

# Session list with Redis backend
praisonai session list --storage-backend redis://localhost:6379

RedisBackend Features

Feature	Description
TTL Support	Automatic expiration with ttl parameter
Key Prefixing	Namespace isolation with prefix parameter
Sub-ms Latency	High-speed caching
Distributed	Shared state across nodes
