   > As to the question @viirya raised in https://github.com/apache/arrow-rs/issues/1333 , when manage memory, the one who allocate it should free it, which means in our case, we need to alloc the struct in rust and pass the pointer to java and then also free the memory in rust.
   
   Simply said, I don't think this is correct. That is the whole point of C data interface. The release callback is designed to be called by not only the one allocates the C data interface structure.
