A company has a media metadata extraction pipeline running on AWS. Notifications containing a reference to a file in Amazon S3 are sent to an Amazon Simple Notification Service (Amazon SNS) topic. The pipeline consists of a number of AWS Lambda functions that are subscribed to the SNS topic. The Lambda functions extract the S3 tile and write metadata to an Amazon RDS PostgreSQL DB instance. Users report that updates to the metadata are sometimes slow to appear or are lost. During these times, the CPU utilization on the database is high and the number of failed Lambda invocations increases. Which combination of actions should a solutions architect take to help resolve this issue? (Choose two.)
