### Describe the enhancement requested The BYTE_STREAM_SPLIT encoder and decoder allocate a `SmallVector` to hold the addresses of the different streams. While this is valid for small number of streams (which is most or all legitimate use cases), very large numbers of streams (e.g. FLBA(100000000)) can trigger a huge temporary memory allocation. ### Component(s) C++, Parquet -- This is an automated message from the Apache Git Service.
