[infinispan-dev] Martin Ribaric -- Migration of Infinispan OData server

[Sebastian Laskawiec]

Hey guys!

I've briefly looked through the code and Apache Olingo. It looks very
interesting!

As far as I can see the project has been designed to be deployed on Tomcat
and use Infinispan Embedded. For me the more interesting usecase would be
to make it available on Infinispan Server (just like REST or Memcached
support). But I realized that we have zero support for this kind of custom
plugins (extensions or data format providers I should say? It's hard to
find a good word for that).

Just thinking out laud - maybe the scope of the project should be larger?
Maybe the proper way of doing this is developing an SPI for deploying
custom 'server extensions' (perhaps as WARs) and implementing OData support
as a proof of service?

But regardless what I've just said, Ribarič, Tomas, great work! Keep it up!

Thanks,
Sebastian
