Thanks @huaxingao , one more question / clarification. In the writer, > field_id has to be unique in the entire schema, otherwise, an Exception will be thrown. what happens if the column ids are not set by the caller? In the reader, > the id in the requested schema will be used to figured out the original ColumnPath. what happens if the file footer doesn't have the column ids (field_id were not set by the writer)? -- This is an automated message from the Apache Git Service.
