> Currently, when you need to pre-allocate space for a record batch or a stream
> (schema + dictionaries + record batches), you must make multiple passes over
> the data structures of interest (and use e.g. {{MockOutputStream}} to compute
> the size of the output buffer). It would be useful to make a single pass to
> "prepare" the IPC payload for both sizing and writing to prevent having to
> make multiple passes
