Scheduled Zambdas
We will cover what scheduled Zambdas are, when you should use them and how to create one. If you have not already read the Writing Zambdas guide, we recommend you do so before continuing.
Overview of Scheduled Zambdas
Scheduled Zambdas run at a regular interval. If desired, you can specify a start and end time frame for them to run.
Defining the rate at which a Scheduled Zambda runs is done using a cron expression. You can read more about cron expressions here (opens in a new tab).
Example use cases:
