mc-pyority-queue 1.0.1

Map colonies priority queue management service for records

Map colonies - priority queue management package

Overview

Pyority-Queue - python priority queue package provides ability to manage queue by handle tasks statuses and report tasks liveness.

Installation:

From PyPi

 $ pip install mc-pyority-queue

Getting Started

Import & Initialize

from mc-pyority-queue.task_handler import TaskHandler

task_handler = TaskHandler('job_type', 'task_type',
    'http://localhost:8081', 'http://localhost:8080/heartbeat', 1.0)

above example uses TaskHanler class and initializing it follow the request params:

task_handler = TaskHandler(job_type, task_type, job_mngr_url, heartbeat_url, interval_ms, logger)

• Dequeue

from mc-pyority-queue.task_handler import TaskHandler

async def main():
    task_handler = TaskHandler('job_type', 'task_type',
    'http://localhost:8081', 'http://localhost:8080/heartbeat', 1.0, logger_instance)

    await task_hanlder.dequeue(interval_ms)


loop = asyncio.get_event_loop()
task = loop.run_until_complete(main())

consume task from the job manager service and start send heartbeat to the heartbeat service

• Reject

 await task_hanlder.reject(job_id, task_id, is_recoverable, reason)

reject handle error by stop sending task's heartbeat and handle task's status - depends if task is recoverable or not.

• ack

await task_hanlder.ack(job_id, task_id)

ack handle completed task - stops sending task's heartbeat and handle complete task status

• update_progress

await task_hanlder.update_progress(job_id, task_id, percentage)

handle task progress - sends job manager updated percentage on progress
