Schedule

This event allows you to set up scheduled invocations of your function.

The plugin automatically configures a trigger and rule to connect your function to the trigger feed from the alarm package.

Configuration

The schedule event configuration is controlled by a string, based on the UNIX crontab syntax, in the format cron(X X X X X). This can either be passed in as a native string or through the rate parameter.

Simple

The following config will attach a schedule event and causes the function crawl to be called every minute.

functions:
  crawl:
    handler: crawl
    events:
      - schedule: cron(* * * * *) // run every minute

This automatically generates a new trigger (``${service}_crawl_schedule_trigger) and rule (${service}_crawl_schedule_rule`) during deployment.

Customise Parameters

Other schedule event parameters can be manually configured, e.g trigger or rule names.

functions:
  aggregate:
    handler: statistics.handler
    events:
      - schedule:
          rate: cron(0 * * * *) // call once an hour
          trigger: triggerName
          rule: ruleName
          max: 10000 // max invocations, default: 1000, max: 10000
          params: // event params for invocation
            hello: world
