Benchmarks for sqlparser. See [the main README](../README.md) for more information.

Note: this is in a separate, non workspace crate to avoid adding a dependency 
on `criterion` to the main crate (which complicates testing without std).

# Running Benchmarks

```shell
cargo bench --bench sqlparser_bench
```

# Profiling

Note you can generate a [flamegraph] using the following command:

```shell
cargo flamegraph --bench sqlparser_bench
```

Here is an example flamegraph:
