CloudWatchTimerLambda

CloudWatchTimerLambda is an AWS-Lambda Java base class that disables its CloudWatch Rule (the rule that triggers your Lambda with a ScheduledEvent) after a timed expiration:
If for no other reason, use CloudWatchTimerLambda to lower billed AWS resources.

Detailed Usage: https://github.com/cellepo/CloudWatchTimerLambda/wiki

Extend CloudWatchTimerLambda by implementing its abstract #process method (to do your concrete Lambda's job).
Your Lambda will then have these benefits when it is run (all occur after processing):

Features

• Stores (if not already stored) an expiration time for the triggering CloudWatch Rule to expire and be disabled
  • The expiration is the sum of the time that storage of the expiration occurs, plus a duration:
    • Duration is configured by Lambda Environment Variable: "SCHEDULED_EVENT_RULE_EXPIRY_DURATION_MILLIS"
  • The expiration is stored in S3
    • Name of its S3 bucket is configured by Lambda Environment Variable: "S3_BUCKET_NAME"
• If expiration is already stored, and current time is after it, then the triggering CloudWatch Rule expires:
  • CloudWatch Rule is disabled
  • Stored expiration is deleted from S3
