We have encountered some issues recently. For example, AWS released a new feature called a better quarter, which greatly helped us. Before that, we faced challenges in vertically scaling our workload. After the release of the new feature, we were able to scale vertically by utilizing sixteen CPU units and a large memory capacity. We also experienced issues with scaling in, as it would abruptly terminate the task. However, AWS introduced a feature called task protection that has been helpful in resolving this issue. Nevertheless, during this period, we were exploring a move to Spark due to the challenges we encountered, which is why I rated the overall product as an eight out of ten.
