When you create a mapping to write to Snowflake, you can specify the size of the local staging .csv file in bytes. Specify the local staging file size property, csvFileSize, in the

Additional Write Runtime Parameters

field in the advanced Snowflake target properties. The default file size is 50 MB.

If the intended file size is 50 MB, calculate the csvFileSize value in bytes, for example 50*1024*1024 and then specify 52428800 as the csvFileSize. For optimal performance, the number and size of the CSV files must be in synchrony.
