> Looks like @nevi-me filed the original ticket -- I wonder if he has any additional context? Hey @alamb @tustvold My recollection is that the idea was that if the precision is low enough, Parquet can write the file to i32 or i64 physicla types to result in smaller files (https://github.com/apache/parquet-format/blob/master/LogicalTypes.md#decimal). There's 2 scenarios: * When reading from Arrow > Parquet, should the behaviour to use the smallest possible physical type based on precision? * When reading from Parquet > Arrow, I suppose Decimal128 makes sense. -- This is an automated message from the Apache Git Service.
