Which statement about Features Per Bulk Write and resource usage is true?

• A. Increasing the chunk size increases system resources.
• B. Increasing the chunk size decreases system resources.
• C. Chunk size has no effect on resources.
• D. Chunk size only affects memory but not CPU.

Answer: (A)

buffering more features before writing means the writer holds a larger in-memory batch and does more work in a single operation. When you raise the number of features per bulk write, the system must allocate space for a bigger batch, which increases peak memory usage. It also does more processing in that bulk write, which raises CPU usage for that operation. Because both memory and CPU (and related I/O patterns) can rise with larger chunks, overall system resources tend to increase. If you use smaller chunks, you produce more frequent, smaller writes with a lower per-batch memory footprint, but with higher write overhead. The idea that there’s no resource impact, or that only memory is affected, isn’t accurate because CPU and I/O behavior also change with batch size. So, increasing the chunk size increases system resources.
