As interesting as this, benchmarking demonstrates that there are no performance gains over the in-memory solution: 

R> microbenchmark::microbenchmark(
   hy_daily_flows(prov_terr_state_loc = "BC", start_date = as.Date("2018-01-01"), end_date = as.Date("2018-12-31")), times = 5
 )
Unit: seconds
                                                                                                                  expr
 hy_daily_flows(prov_terr_state_loc = "BC", start_date = as.Date("2018-01-01"),      end_date = as.Date("2018-12-31"))
      min       lq     mean  median       uq      max neval
