Drumpler 1.0.9

Framework for rapidly developing a restful API that requires post processing

Drumpler

Drumpler is a general-purpose application designed to facilitate efficient workflow automation through RESTful API interactions and job processing. Built on Flask and SQLAlchemy, this application serves as a robust backend for capturing, storing, and processing HTTP requests in a scalable manner. The application is split into two main components: drumpler.py for handling RESTful API requests and mammoth.py for querying the API and processing jobs asynchronously.

High Level Overview

Features

• RESTful API Endpoints: Secure and scalable endpoints for handling HTTP requests, including POST, GET, PUT, and DELETE operations.
• Database Integration: Utilizes SQLAlchemy for ORM-based interactions with Postgres.
• Job Processing: Facilitates the asynchronous processing of tasks with support for multi-threading and multi-processing, ensuring efficient workflow automation.
• Event Logging: Detailed event logging for each HTTP request, job processing and related events, allowing for easy tracking and management of tasks.

Prerequisites

Before you begin, ensure you have the following installed:

• Python 3.6 or later
• PostgreSQL

Installation

Install Drumpler via pip: pip install Drumpler

Configuration

Create a .env file in the root directory of the application with the following contents:

AUTHORIZATION_KEY=AUTH_KEY_HERE
DRUMPLER_HOST=IP_HERE
DRUMPLER_PORT=PORT_HERE
DRUMPLER_DEBUG=BOOL_FLAG
DB_NAME=DB_NAME_HERE
DB_HOST=DB_HOST_HERE
DB_USER=DB_USER_HERE
DB_PASS=DB_PASS_HERE

Replace your_database_uri_here and your_authorization_key_here with your actual database URI and desired authorization key.

Using the Application - Drumpler

To create a Drumpler RESTful server, the following is a sample implementation:

import drumpler

# Now, you can create an instance of the Drumpler class
app = drumpler.Drumpler(host="0.0.0.0", port=5000, debug=True)  # Adjust as necessary

# And call the run method on this instance
app.run()

API Endpoints

Drumpler exposes the following endpoints for interacting with its system:

• POST /request: Submit a new request for processing.
• GET /request/<int:request_id>: Retrieve a specific request by its ID.
• GET /request/next-unhandled: Fetch the next unhandled request.
• PUT /request/<int:request_id>: Update the status of a request.
• DELETE /request/<int:request_id>: Delete a specific request.

Using the Application - Mammoth

To create a Mammoth (request-processor), the following is a sample implementation:

from drumpler.mammoth import Mammoth

def custom_process_function(session, request, job_id):
    # this is the driver method for your customized workflow
    pass

# Initialize Mammoth
DRUMPLER_HOST = "http://127.0.0.1"
DRUMPLER_PORT = 5000  # Adjust the URL/port as necessary
DRUMPLER_URL = f"{DRUMPLER_HOST}:{DRUMPLER_PORT}"  # Adjust the URL/port as necessary
MAMMOTH_WORKERS = 1
mammoth = Mammoth(process_request_data=custom_process_function, drumpler_url=DRUMPLER_URL, workers=MAMMOTH_WORKERS)

if __name__ == "__main__":
    print("Starting Mammoth... Press CTRL+C to stop.")
    mammoth.run()
