sqlite-scheduler 0.1.3

A Rust-powered Python library for scheduled SQLite operations.

sqlite-scheduler

A Rust-powered Python library for scheduled SQLite operations.

• Python 3.9+
• Rust-backed SQLite I/O via rusqlite
• Built-in interval scheduler running in a native thread
• Optional integration with the popular Python schedule package

Build

maturin develop

Usage

With the Python schedule package

import sqlite_scheduler
import schedule
import time

def job():
    sqlite_scheduler.execute_sql(
        "app.db",
        "INSERT INTO logs(msg) VALUES (?)",
        parameters=["heartbeat"],
    )

schedule.every(10).seconds.do(job)
while True:
    schedule.run_pending()
    time.sleep(1)

With the built-in scheduler

from sqlite_scheduler import SqliteScheduler

scheduler = SqliteScheduler("app.db")
scheduler.add_interval_job(10, "INSERT INTO logs(msg) VALUES ('tick')")
scheduler.start(blocking=False)
# ...
scheduler.stop()

Basic CRUD

import sqlite_scheduler

sqlite_scheduler.execute_sql(
    "app.db",
    "CREATE TABLE IF NOT EXISTS users (id INTEGER PRIMARY KEY, name TEXT)",
)

rows = sqlite_scheduler.execute_sql(
    "app.db", "SELECT * FROM users", fetch=True
)
print(rows)  # [{'id': 1, 'name': 'Alice'}, ...]
