Testing result, it looks good:
```rust
cargo run --profile release-nonlto --target aarch64-apple-darwin --bin
dfbench -- clickbench --queries-path ./benchmarks/queries/clickbench/queries/
-p ./benchmarks/data/hits_partitioned/ -q 21 -i 1 --debug
Finished `release-nonlto` profile [optimized] target(s) in 0.28s
Running `target/aarch64-apple-darwin/release-nonlto/dfbench clickbench
--queries-path ./benchmarks/queries/clickbench/queries/ -p
./benchmarks/data/hits_partitioned/ -q 21 -i 1 --debug`
Running benchmarks with the following options: RunOpt { query: Some(21),
common: CommonOpt { iterations: 1, partitions: None, batch_size: None,
mem_pool_type: "fair", memory_limit: None, sort_spill_reservation_bytes: None,
debug: true }, path: "./benchmarks/data/hits_partitioned/", queries_path:
"./benchmarks/queries/clickbench/queries/", output_path: None }
Q21: SELECT "SearchPhrase", MIN("URL"), COUNT(*) AS c FROM hits WHERE "URL"
LIKE '%google%' AND "SearchPhrase" <> '' GROUP BY "SearchPhrase" ORDER BY c
DESC LIMIT 10;
Query 21 iteration 0 took 1162.6 ms and returned 10 rows
