How to implement Cron jobs with multiple databases.

[Mandeep Kaur]

I have build a saas product with angular integrated with golang rest api, this project provide vendors of a firm to maintain their store ( like shopify but for a small organization only ) where each vendor has a different database. on daily basis system should run corn jobs to send email and notification to their merchants. Each vendor has store setup on a sub-domain like merchant1.store.com and db with name merchant_1_db.

I used golang schedules to setup cron jobs but they are not running per vendor. I need help on how to setup parallel cron jobs for various merchants.

The 'target' string is prepended to your app's hostname. So an option would be to create multiple tasks on a single cron job. For example: 

cron:
- description: "daily merchant1 mailout"
  url: /mail/merchant1
  schedule: every 24 hours
- description: "daily merchant2 mailout"
  url: /mail/merchant2
  schedule: every 24 hours
- description: "daily merchant3 mailout"
  url: /mail/merchant3
  schedule: every 24 hours
