Scheduler

Introduction

The service scheduler is responsible for a periodical execution of integration flows.

Implementation Service File

Technologies used

  • Cron-Deamon

How it works

In the Open Integration Hub there is a great number of active integration flows to be executed periodically. Each integration can be configured with a Cron expression defining flow’s execution interval. Let’s consider the following Cron expression:

*/3 * * * *

The cron expression above executes an integration flow at every 3rd minute starting from the flow’s start time.

With the following Cron expression a flow is executed every Sunday at 6:00 am:

0 6 * * 7

The Scheduler iterates over all active integration flows and evaluates their Cron expressions. Is a flow due to be executed, Scheduler tells the Resource Coordinator to deploy the integration flow for execution.
