For BigQuery and Databrics, Arrow-formatted record batches are returned from the server in a format that's not strictly compatible with the Arrow stream format due to the way that the schema and the array data are split. A change was recently made to the C# Arrow library to allow these to be deserialized independently, which means that we no longer need to indirect through a Stream -- saving on both CPU and memory and reducing pressure on the GC.
