What are some common challenges faced by Teradata developers when optimizing large-scale data queries?

Teradata Developers often encounter challenges such as managing complex joins, ensuring efficient indexing, and minimizing data skew when optimizing large-scale queries. They must balance query performance with system resource usage, especially in environments handling massive datasets. Effective collaboration with data architects and DBAs is essential to design optimal data models and implement best practices for partitioning and workload management.
