Subject Re: Using Java ignite clients and calling them from c++ using JNI v/s using c++ ignite clients directly
Date Wed, 09 Aug 2017 13:06:02 GMT
Hi,

This depends on the feature scope you will need in C++, but in general,
it is not trivial task to implement some of Ignite features in C++. For
example, that's true that you have to specialize BinaryType in C++ now to
work with it, but if you will choose to implement your own solution you will
need to implement your own serialization/de serialization protocol for
objects
and re-invent some solutions, which is already implemented in C++ client.

So, in general it looks to me as the second way is much simpler.

Also, if you want some feature in C++ client which is not there now, you
can always implement it and contribute to project as Ignite is opensource
and community driven. This way you'll get your feature, help of the
community with development and you will also develop the project, which
will help entire community.

Best Regards,
Igor
