Aim to produce data files that are between 100 MB and 250 MB in size, compressed.

Load data from files in a cloud storage service in a different region or cloud platform from the service or region containing the Snowflake account, to save on cost.

Enclose fields that contain delimiter characters in single or double quotes.

Split large files into a greater number of smaller files to distribute the load among the compute resources in an active warehouse.

When planning which warehouse(s) to use for data loading, start with the largest warehouse possible.

Partition the staged data into large folders with random paths, allowing Snowflake to determine the best way to load each file.
