What is the type of the field in the parquet file itself? A string? If so, then the parquet metadata is going to be storing min/max using lexical comparison which might not be the same min/max you'd get doing temporal comparison. So I don't know if it would be valid to use these statistics for filtering. I think I might not be understanding though. A few questions: What is the type of the column in the file itself (e.g. in the parquet metadata, is this string?) What is the type of the column in the dataset schema (looks like timestamp) What is the type of literal in the filter (looks like timestamp) -- This is an automated message from the Apache Git Service.
