Function mz_persist::indexed::columnar::arrow::decode_trace_arrow

pub fn decode_trace_arrow<R: Read + Seek, T: Timestamp + Codec64>(
    r: &mut R,
    metrics: &ColumnarMetrics
) -> Result<BlobTraceBatchPart<T>, Error>

Decodes a BlobTraceBatchPart 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.
