eq operator doesn't work on binary data

[ozgrakkurt]

Hello,

I am trying to use datafusion to query multiple parquet files.

Comparing a binary column with binary literal using eq operator doesn't work.

I expect this to just work since eq works on strings.

I have this code:

let address = prefix_hex::decode::<Vec<u8>>(&self.address).map_err(Error::InvalidHexInAddress)?;
let mut expr = col("log.address").eq(lit(address));

and I get this error:

failed to execute query:\nArrow error: External error: Arrow error: External error: Execution error: Arrow error: External error: Arrow error: External error: Execution error: Arrow error: External error:
Internal error: Data type Binary(\"161,250,161,19,203,229,52,54,223,40,255,10,238,84,39,92,19,180,9,117\") not supported for scalar operation 'eq' on dyn array.
This was likely caused by a bug in DataFusion's code and we would welcome that you file an bug report in our issue tracker

I tracked the error message to here

Shouldn't there be a match arm for Binary data?

Thanks for the report @ozgrakkurt

Yes I think you are exactly correct.
