Uwe L. Korn commented on ARROW-417:
-----------------------------------

{{same-sized chunks}} is a lot easier as we can then just call Equals methods 
of the underlying arrays. {{equal contents with differing chunk size}} is more 
complicated as it needs additional logic.

> C++: Add Equals implementation to compare ChunkedArrays

> The {{arrow::ChunkedArray}} class is missing a method to compare it to other 
> {{arrow::ChunkedArray}} instances. There should be one implemented in the way 
> the {{Equals}} implementation is done in the subclasses of {{arrow::Array}} 
> and is needed to provide a way to compare {{arrow::Column}} instances.
