What are some common challenges faced by SQL data warehouse developers when optimizing query performance?

SQL Data Warehouse Developers often encounter challenges related to slow-running queries, suboptimal indexing, and large data volumes that can impact system performance. Balancing data normalization with the need for fast reporting, managing partitioned tables, and ensuring efficient ETL processes are typical hurdles. Developers regularly collaborate with data architects and BI analysts to identify bottlenecks, rewrite queries, and implement best practices for indexing and partitioning to maintain optimal performance.
