> When the arrow parquet reader read data from parquet files, I remember even in parquet the files, the data is dictionary encoded(string types with low cardinality), the arrow parquet reader will not convert it to Arrow Dictionary type. I believe @tustvold changed this a while ago so that the Dictionary is preserved (and then I think datafusion hydrates them) -- https://github.com/apache/arrow-rs/pull/1180 -- This is an automated message from the Apache Git Service.
