High CPU with low disk reads suggests queries are being served from the in-memory cache, which is actually a sign of good caching behavior.
3. Which AWS service is the primary recommended method for bulk-loading data into Amazon Redshift?
The COPY command loads data in parallel from S3, DynamoDB, EMR, or SSH sources and is far faster than row-by-row inserts.
