Hi, I looked through Arrow's docs about its formats and APIs.
But I am still somewhat confused about typical usecases of Arrow. As in my understanding, the goal of Arrow is to eliminate the (de)serialization costs among different data analytic systems, since it has the common format. But, it still needs some data conversion between Arrow format and language native format, right? For example, you have to convert Arrow columnar-based format to C++ row-based format. Or is there any usecase to directly conduct data analysis on Arrow's format? Best, Tao
