This article is the first in a series that demonstrates how to utilize the Couchbase Eventing Service to execute multiple scheduled tasks within the database itself, mimicking cron-like functionality without additional infrastructure. The focus of this installment is on executing fixed user routines, specifically JavaScript functions defined within an Eventing Function. The Couchbase Eventing Service provides a flexible framework for processing document changes in real-time, enabling scalable cloud-based functions that interact with Couchbase services. The article details how to create a distributed crontab system using Couchbase, with JSON control documents defining the schedules and actions. It explains the limitations of current Couchbase versions, the workaround solutions implemented, and the setup process for deploying these Eventing Functions. The series will continue to explore more advanced scheduling capabilities, including dynamic N1QL statements and JavaScript functions.
