Chronos Scheduler

The Chronos Scheduler allows you to automate routine tasks in Gluesync, such as starting/stopping entities and pipelines, or running snapshots on a schedule. This guide will walk you through setting up and managing scheduled tasks.

Creating a New Schedule

Navigate to the Scheduler section in the Gluesync Core Hub

Before creating a new schedule, ensure you have set your preferred timezone using the timezone selector in the top right corner of the screen.
Timezone

Any schedules you create will use the currently selected timezone, and changing the timezone later will not affect existing schedules.

Change Timezone

Click the "New +" button in the top right corner

New Button

Fill in the schedule details

New Schedule

  • Name: A descriptive name for your schedule

  • Repeating Options: Choose between the repeating options (Days of the week, Hours of the day)

  • Target: Select the specific entity or pipeline to run/pause

  • Action Type: Select the type of action to execute (Run CDC, Pause/Stop, Run Snapshot)

  • Schedule: Configure the schedule using the visual picker and save the schedule

Repeating Options

Repeating Options

For common scheduling needs, use the simple schedule picker to select from the following options:

Day Selection:

  • A row of checkboxes labeled with day abbreviations (Mon, Tue, Wed, etc.) is displayed

  • Click on each day of the week when you want the task to run

  • Selected days will be highlighted in the interface

Time Configuration:

  • Time input field appears near the day selection

  • Enter the time in 'hh:mm' 12-hour format (e.g., '2:30')

  • Select either 'AM' or 'PM' from the dropdown menu

  • The time picker will validate your input to ensure it’s in the correct format

  • The scheduled time will be based on the timezone you’ve selected in the top right corner

Example Scenarios:

  • For a task that runs every weekday at 9:00 AM:

  • Check Mon, Tue, Wed, Thu, Fri

  • Enter '09:00' in the time field

  • For a task that runs on weekends at 11:30 PM:

  • Check Sat, Sun

  • Enter '11:30' in the time field and select 'PM' in the near field

Target Selection

Select a Pipeline

Select Pipeline

  • Choose the pipeline you want to schedule from the dropdown menu

  • The list shows all available pipelines in your environment

Select Entities (optional)

Select Entities

  • After selecting a pipeline, you can optionally choose specific entities

  • To select entities:

  • Click on the entities dropdown

  • Check the boxes next to the entities you want to include

  • Selected entities will be highlighted

Leaving all entities unselected will apply the schedule to the entire pipeline.
