MSK Best Practices

  1. 1Use Athena workgroups to separate query history and control costs per team
  2. 2Enable Glue Data Catalog encryption and resource-level IAM policies
  3. 3Use partition projection in Athena instead of MSCK REPAIR TABLE for faster queries
  4. 4Set query result location to an S3 bucket with lifecycle expiration (7 days)
  5. 5Monitor with CloudWatch — set alarms on query scan volume to avoid cost surprises
