 It shares the root `uv.lock` with PyAthena, which it uses from the workspace checkout.
 Locally and in CI, its virtual environment is `benchmarks/.venv`, separate from the root `.venv`.
 On the EC2 instance, the dedicated checkout's root `/opt/pyathena/.venv` holds the benchmark environment.
+The `polars1` and `polars2` dependency groups select Polars 1.x or 2.x, which PolarsCursor reads with different code paths.
+The environments above have `polars1`; a second environment beside each, `benchmarks/.venv-polars2` or `/opt/pyathena/.venv-polars2`, has `polars2`.
+The root `pyproject.toml` declares both groups and the root `dev` group as conflicting, so `uv.lock` resolves each of them separately.
+The benchmark's default dependency groups include `polars1`; a sync with `--no-default-groups` needs `--group polars1` or `--group polars2`, or it installs whichever Polars version the lock resolves without them.
 The root `uv build -v` still builds only PyAthena, including a wheel built from its sdist.
 Benchmark dependencies do not become PyAthena runtime dependencies, and `uv sync --group dev` at the root does not install them.

 `--chunksize` keeps only the given chunk sizes, with 0 for reads without chunks, in `plan`, `run`, and `jobs`; `jobs` passes it to each job and adds it to the job ID.
 `jobs` accepts `--warmups` and `--repetitions` too; with either option, every job that is not split carries both values as arguments, so one queue can combine jobs with different trial counts under one stored configuration.
 `queue --jobs` accepts several job files, rejects duplicate job IDs, and orders the combined jobs as `jobs` orders one selection.
+`jobs --environment polars2` runs the selected jobs with Polars 2.x: each job names the environment, and its ID ends with `-polars2`, so one queue can hold the same cases for both Polars versions.
+A worker runs such a job with the interpreter of `.venv-polars2` beside its own environment, and refuses to start if a job's environment is missing on its host; start the worker from the default environment, whose interpreter runs the other jobs.
+Select the families that use Polars, `polars` and `sqla_polars`, for this environment.
 
 Deploy a new stack with the fleet size under its own name; changing `FleetSize` on an existing stack does not wait for the added hosts to finish bootstrap.
 `QueueName` names the queue that every host consumes: after bootstrap, each host starts a worker with the stack's results location from its user data, also written to `results-location.txt` next to `stack-id.txt`, and the worker waits until a queue of that name is published; this includes the hosts that the group launches later to replace interrupted Spot Instances.
