    A company has an application that runs on AWS Lambda and sends logs to Amazon CloudWatch Logs. An Amazon Kinesis data stream is subscribed to the log groups in CloudWatch Logs. A single consumer Lambda function processes the logs from the data stream and stores the logs in an Amazon S3 bucket.

    The company’s DevOps team has noticed high latency during the processing and ingestion of some logs.

    Which combination of steps will reduce the latency?
