Triage Guide for TABLE_DATA_STALE

Understand​

This alert indicates that the data in the DynamoDB table has not been updated recently, beyond the specified threshold.

Validate​

To validate this alert:

  1. Manually check the latestStreamLabel for the table through the AWS Management Console or CLI.
  2. This policy runs reactively, so it doesn't scan on a fixed schedule.

Triage​

Impact​

Stale data can lead to outdated results in applications depending on the table. It could indicate an issue in upstream data pipelines or a change in data usage patterns.

Remediation​

If the table is supposed to be updated regularly, identify and fix the issue causing the delay.

Act​

  1. Investigate upstream data sources and pipelines to ensure data updates are flowing as expected.
  2. Use AWS CloudWatch metrics and logs to debug any issues.

Reflect​

If this was not a good use of time, consider lowering the sensitivity of the threshold, adjusting policy parameters, or disabling the policy.
