Motivation

We will introduce arrow compression #187. However, Currently, the client calculates the batch size using the data before compression. This can cause a discrepancy between the actual batch size sent to the server and the batch size configured by the user, which in turn affects the compression efficiency. Therefore, we need to introduce an estimator to continuously update the latest compression ratio, making the compressed batch size closer to the user's specified value.
