Review Comment:
   one suggestion, added benchmark always use topk, we should add some 
benchmark do not use topk, then we can compare, like below
   ```rust
       let ctx = rt
           .block_on(create_context(partitions, samples, false, false, false))
           .unwrap();
       c.bench_function(
           format!(
               "string aggregate {} time-series rows [Utf8]",
               partitions * samples
           )
           .as_str(),
           |b| b.iter(|| run_string(&rt, ctx.clone(), limit, false)),
       );
   
       let ctx = rt
           .block_on(create_context(partitions, samples, true, false, false))
           .unwrap();
       c.bench_function(
           format!(
               "string aggregate {} worst-case rows [Utf8]",
               partitions * samples
           )
           .as_str(),
           |b| b.iter(|| run_string(&rt, ctx.clone(), limit, false)),
       );
   ```
