	ctx := sf.WithArrowAllocator(
		context.Background(),
		mem,
	)

	db, err := sql.Open("snowflake", connUrl)
	require.NoError(t, err)
	defer db.Close()

	conn, err := db.Conn(ctx)
	require.NoError(t, err)
	defer conn.Close()

	rows, err := conn.QueryContext(ctx, "select 1")
	require.NoError(t, err)
	defer rows.Close()
	for rows.Next() {
		var v int

		assert.Equal(t, 1, v)
	}
