> Subject: c++ DataFileWriter not doing validation
> Hi List,
> I'm working with the c++ bindings to try to write data to avro files.
> Much of the documentation assumes that the types to be written (and the code to write the data) are generated using avrogencpp.
> In my case I have an existing set of type/struct hierarchies that I'm trying to write so I don't want to use the output of avrogencpp >directly. Instead I am producing code that is very similar to what avrogencpp outputs but is adapted to suit my types.
> What I'm finding is that the c++ DataFileWriter does no validation between the schema that I provide and the datums that get written. As such any discrepancy between the schema and the datums that are written causes the file to be corrupted and essentially unreadable.
> I see that there is a ValidatingEncoder class that can be used when serialising to a memorystream (as per the Getting Started docs) but there doesn't appear to be any method for using this encoder with the DataFileWriter.
> Am I missing something? Is there a preferred way to make the writer do validation?
I never got any responses to this so I assume either no-one knows, or no-one actively uses the C++ bindings anymore?
My basic question boils down to can the DataFileWriter be made to do validation against the schema?
Any help much appreciated.
