[GitHub] [arrow] Yuhta opened a new issue #9239: Filter out columns in compressed IPC format

Yuhta opened a new issue #9239:
URL: https://github.com/apache/arrow/issues/9239


   We have a use case in C++ to get several columns out from a compressed table (serialized in IPC streaming format) *without decompressing then compressing the data*.  I can see from the flatbuffers definition that each columns are serialized and compressed separately, so this is doable in theory.  I am wondering if there is already some code in arrow-cpp to do this, or we have to generate our flatbuffers code and manipulate on the IPC bytes ourselves?
