Why does Snowflake recommend file sizes of 100-250 MB compressed when loading data?
Snowflake recommends file sizes of 100-250 MB compressed when loading data because it allows optimization of parallel operations. Larger compressed files enable more efficient use of resources by leveraging parallel processing, leading to faster data loading and better performance.
D correct
To optimize the number of parallel operations for a load, we recommend aiming to produce data files roughly 100-250 MB (or larger) in size compressed.

D. Allows optimization of parallel operations
Correct. Another thing to keep in mind in actual operation in utilizing, for example a Snowpipe, it is less costly to have lots of data in large compiled files flowing through a Snowpipe. For every 1,000 files queued, you have to pay for 0.06 credits. I have tested this myself.
