   > Good point. I hadn't traced all the way down to what glog does in this 
case and I assumed Python was aborting due to an uncaught C++ exception calling 
terminate. I [now see that glog is aborting 
though](https://github.com/google/glog/blob/master/src/logging.cc#L1900). 
Perhaps it would make sense for arrow to use glog's 
[`InstallFailureFunction`](https://github.com/google/glog/blob/53d58e4531c7c90f71ddab503d915e027432447a/src/logging.cc#L1896)
 to instead throw an exception rather than aborting? Since Arrow uses 
exceptions in other places that seems like it would be more consistent.
   
   GLog is an optional dependency. The purpose of these checks is to act just 
like C asserts, for example to test internal invariants. They abort on purpose.
   
   For proper error reporting, Arrow C++ uses its own `Status` class and is not 
meant to raise exceptions (the Parquet C++ codebase is an... exception to this 
rule, for historical reasons).
