   We've run into this issue and I'd like to work on a fix. It appears that the C++ implementation handles this transparently by re-writing any dictionaries that have changed, so it should be possible to implement a similar solution in Java: https://github.com/apache/arrow/blob/018e7d3f9c4bcacce716dd607994486a31ee71bb/cpp/src/arrow/ipc/writer.cc#L1121
