What is the optimal compressed file size for loading files into Snowflake?

1. 1 - 10 MB

2. 50 - 200 MB

3. 10 - 100 MB

4. 100 - 500 MB

The correct answer is: 10 - 100 MB

The optimal compressed file size for loading files into Snowflake is typically in the range of 10 - 100 MB. This size strikes a balance between efficient data transfer and the overhead associated with file management and loading processes. Files that are too small may lead to inefficient loading due to the higher overhead in processing numerous small files, which can slow down the overall ingestion process. Conversely, larger files can increase the risk of issues during loading, such as memory constraints or timeouts. When you load data into Snowflake, it processes the data in parallel, and having files in the 10 - 100 MB range allows for effective utilization of this parallelism without causing excessive strain on system resources. This optimal size supports quicker loading times and better performance, facilitating the handling of larger datasets within a manageable framework.
