    Hi gents,

    IMHO the below question is ambiguous and requires some word tuning: while small files in a S3 bucket scream for a parquet conversion answer, the ‘ML query’ word is confusing as I personally assumed that it is Sagemaker that will connect, so ruled out Parquet

    A Machine Learning Specialist is migrating hundreds of thousands of records in CSV files into an Amazon S3 bucket. Each file has 150 columns and is about 1 MB in size. Most of the Machine Learning (ML) queries will span a minimum of 5 columns. The data must be transformed to minimize the query runtime.

    Hello Klimok,

    Thanks for your feedback. I appreciate it.

    I understand what you mean. Happy to change the wording here to avoid confusion for others as well.

    Please let me know if you still have any questions.
