> This fixing looks nice to me, but I'm a bit confused why `schema.metadata()` is extracted to file-metadata, @wgtmac do you know the context here? I found this from https://github.com/apache/arrow/pull/5077: ``` Add ArrowWriterProperties::store_schema() option which stores the Arrow schema used to create a Parquet file in a special ARROW:schema key in the metadata, so that we can detect that a column was originally DictionaryArray. This option is off by default, but enabled in the Python bindings. We can always make it the default in the future ``` -- This is an automated message from the Apache Git Service.
