> Currently, one can only export a record batch to a file:
> {code:java}
> record <- arrow::record_batch(data.frame(a = c(1,2,3)))
> record$to_file()
> {code}
> But to improve performance in Spark's R bindings through sparklyr an
> improvement is to support streams returning R raw's as follows:
> {code:java}
> record <- arrow::record_batch(data.frame(a = c(1,2,3)))
> record$to_stream(){code}
