They said you need to prepare the files to copy, maybe the mean we should make them less than 1MB ? so it will be A else would be B !!!!

After reading the other questions oh this topic I go with A because the relevant part seems to be the compression.

The answer is A Compression doesn't not only help to reduce the size or space occupied by a file in a storage but also increases the speed of file movement during transfer

Selected Answer: A PolyBase can't load rows that have more than 1,000,000 bytes of data. When you put data into the text files in Azure Blob storage or Azure Data Lake Store, they must have fewer than 1,000,000 bytes of data. This byte limitation is true regardless of the table schema. All file formats have different performance characteristics. For the fastest load, use compressed delimited text files. Split large compressed files into smaller compressed files.

PolyBase can load more than 1 mln rows since SQL Server 2019 https://learn.microsoft.com/en-us/sql/relational-databases/polybase/polybase-versioned-feature-summary?view=sql-server-ver16

A is correct ,with copy command PolyBase COPY Needs CONTROL permission Relaxed permission Has row width limits No row width limit No delimiters within text Supports delimiters in text Fixed line delimiter Supports custom column and row delimiters Complex to set up in code Reduces amount of code

It's just a copy to storage so zipping it will work fine.
