AWS Clean Rooms announces support for join and partition hints for SQL queries, enabling optimization of join strategies and data partitioning for improved query performance and reduced costs. This launch enables you to apply SQL hints to your queries using comment-style syntax in pre-approved analysis templates as well as ad hoc SQL queries. You can now optimize large table joins using a broadcast join hint and you can improve data distribution with partition hints for better parallel processing. For example, a measurement company analyzing how many households viewed a live sports event uses a broadcast join hint on their lookup table to improve query performance and reduce costs.
With AWS Clean Rooms, customers can create a secure data clean room in minutes and collaborate with any company on AWS or Snowflake to generate unique insights about advertising campaigns, investment decisions, and research and development.
