As long as you pick the solution that best fits with your requirements, you won't find that performance is a problem. It's good.
Qlik Compose offers effective modeling and code generation for data warehouse creation with minimal effort. It integrates multiple source systems and automates data lifecycle reports, delivering scalability and stability. Despite its excellent graphical data representation, it lacks ETL process monitoring and struggles with high data volumes due to missing batching capabilities. Technical support and documentation improvements, along with better performance for processing large data volumes, are needed to enhance its efficiency.
