In a multi-writer workflow, why might you place the GeoTIFF writer before the Excel writer?

• A. To ensure alphabetical processing
• B. To take advantage of caching behavior and reduce wait time
• C. To guarantee data integrity
• D. To simplify error handling.

Answer: (B)

The main idea is how OS-level caching affects multi-writer I/O. When you run the GeoTIFF writer first in a multi-writer workflow, a large amount of data is produced and written, which tends to populate the file system and memory caches. When the Excel writer runs afterward, its output operations can leverage that warmed cache, reducing disk latency and wait time for writes. In other words, sequencing the heavier, cache-friendly write first helps the system serve subsequent writes more quickly, improving overall throughput. This is a performance-oriented reason, not about data order, correctness, or simpler error handling. The other options don’t address the performance gain you get from caching and reduced wait times.
