> As discussed on some other bugs, there are some parquet-cpp DCHECKs on the
> number of values decoded that really should be exceptions. When invalid
> Parquet files are read, it is possible for the decoders to return less values
> than expected and this should be signaled back to the user even in non-debug
> mode and it should not be a crash in debug mode. A fuzzer I have been running
> managed to create two examples that crashed parquet-cpp due to the DCHECKs.
> These don't currently crash the non-arrow cpp interfaces for reading parquet
> but we might consider making those methods also throw exceptions in these
> situations.
