PostgreSQL

PostgreSQL is the recommended database for production Memori deployments. Full concurrent write support, connection pooling, and cloud-ready.

Install

pip install memori psycopg2-binary

Quick Start

PostgreSQL Connection

from memori import Memori
from sqlalchemy import create_engine
from sqlalchemy.orm import sessionmaker

engine = create_engine(
    "postgresql+psycopg://user:password@localhost:5432/memori_db",
    pool_pre_ping=True
)
SessionLocal = sessionmaker(bind=engine)

mem = Memori(conn=SessionLocal)
mem.config.storage.build()

Complete Example

import os
from sqlalchemy import create_engine
from sqlalchemy.orm import sessionmaker
from memori import Memori
from openai import OpenAI

engine = create_engine(
    os.getenv("DATABASE_URL"),
    pool_pre_ping=True,
    pool_size=10,
    max_overflow=20,
    pool_recycle=300
)
SessionLocal = sessionmaker(bind=engine)

client = OpenAI(api_key=os.getenv("OPENAI_API_KEY"))
mem = Memori(conn=SessionLocal).llm.register(client)
mem.attribution(entity_id="user_123", process_id="my_agent")
mem.config.storage.build()

response = client.chat.completions.create(
    model="gpt-4o-mini",
    messages=[{"role": "user", "content": "I'm a senior engineer at Google."}]
)
print(response.choices[0].message.content)

mem.augmentation.wait()
facts = mem.recall("job title and company")
print(facts)

SSL Connections

For cloud-hosted PostgreSQL, use SSL:

engine = create_engine(
    "postgresql+psycopg://user:password@host:5432/memori_db"
    "?sslmode=require",
    pool_pre_ping=True
)

Mode	Description
`require`	SSL required, no certificate verification
`verify-ca`	SSL + verify server certificate
`verify-full`	SSL + verify certificate + hostname
