Function persist::indexed::columnar::arrow::decode_trace_arrow

pub fn decode_trace_arrow<R: Read + Seek>(
    r: &mut R
) -> Result<BlobTraceBatch, Error>

Decodes a BlobTraceBatch from the Arrow file format.

NB: This is currently unused, but it’s here because we may want to use it for the local cache and so we can easily compare arrow vs parquet.
