   ## Reading from CSV
   
   ```
   $ ../target/release/h2o group-by --query 1 --path /mnt/bigdata/h2oai/N_1e7_K_1e2_single.csv
   Running benchmarks with the following options: GroupBy(GroupBy { query: 1, path: "/mnt/bigdata/h2oai/N_1e7_K_1e2_single.csv", debug: false, mem_table: false })
   Executing select id1, sum(v1) as v1 from x group by id1
   h2o groupby query 1 took 1793 ms
   ```
