Task Lifecycle

This document details the complete lifecycle of a task: enqueuing, listing, reserving, extending leases, acknowledging, rescheduling, and SSE snapshots.

Task States

A task moves through the following states:

pending — Waiting for its scheduled time. Not yet visible to workers.
available — Scheduled time has elapsed; ready for reservation.
reserved — Held by a worker under a lease.
completed — Acknowledged and removed by the worker.

If a lease expires without acknowledgement, the task returns to available.

Enqueuing a Task

Create a new task with an id, payload, future time (or delay), and optional labels:

curl -X POST "https://api.hola.cloud/schedulers/sched-a1b2c3d4-e5f6-7890-abcd-ef1234567890/tasks" \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{

    "payload": {

      "report_id": "rpt-5678"

5}
