Can the number of COPY operations exceed the number of data files being loaded?

Yes, it can exceed
No, it cannot exceed
It depends on the warehouse size
Only for small files

The correct answer is: No, it cannot exceed

The correct answer is that the number of COPY operations cannot exceed the number of data files being loaded. When executing a COPY statement in Snowflake, each operation corresponds to loading a specific file. Thus, if you have a set number of data files, the COPY command will only initiate the same number of loading operations. Since each file can be processed in its own COPY operation, the operations are directly tied to the number of files. Therefore, it’s not feasible to have more COPY operations than there are data files, as there wouldn’t be additional files for the COPY statements to load. The other choices, such as suggesting it can exceed the number of files or depends on warehouse size, do not accurately reflect how the COPY command functions since it operates on a one-to-one basis between files and operations. Additionally, implying that only small files could change this dynamic does not hold up because it’s fundamentally about the file count rather than file size.
