> When arrow-rs reads RLE-encoded strings from a Parquet file, it decodes them into dictionary arrays. I think you need to configure the parquet reader with a schema that specifies Dictionary as the data type when reading such a column from parquet files (we use this at InfluxData). However, I don't think there is way to do this via SQL today in DataFusion, though you can do it programmatically (by providing a schema to the table provider) -- This is an automated message from the Apache Git Service.
