A company uses an Amazon Redshift cluster to ingest data from various sources. The data is shared with other internal applications for analysis and reporting. The cluster has eight ra3.4xlarge nodes. Data ingestion runs daily from midnight to 8 AM and takes 3 hours. The cluster has 85% average CPU utilization during ingestion. The cluster uses on-demand node pricing and is paused outside of the 8-hour daily ingestion window. Snapshots are enabled on the cluster. The company wants to optimize this workload to reduce costs. Which solution will meet these requirements?
