Mitigate cold starts in your Java Lambda functions with Datadog and AWS Lambda SnapStart

This AWS article highlights that Lambda functions have limited ephemeral storage (/tmp) and exceeding this limit causes errors. It details how to monitor this storage using CloudWatch metrics like `DurationSeconds` and `MaxMemoryUsed`, allowing you to identify functions nearing the limit and optimize code for efficient storage use. Effectively monitoring ephemeral storage helps prevent function failures and ensures reliable performance.
