QueryExecutor class abstract
A query executor is responsible for executing statements on a database and return their results in a raw form.
This is an internal api of drift, which can break often. If you want to
implement custom database backends, consider using the new backends API.
The NativeDatabase implementation
might be useful as a reference. If you want to write your own database
engine to use with drift and run into issues, please consider creating an
issue.
