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

Hello everyone :)
I am enclosing Martin's email and sending it from my email address because
he sent it twice already and we can't see his emails from his gmail address

all reactions from this thread, please make sure you include him in CC

Thank you!

Hello Infinispan community,
let me introduce myself shortly, my name is Martin Ribarič and I studied
Masaryk University – Faculty of Informatics in Brno. I wrote my bachelor
thesis on topic: Migration of Infinispan OData server. I would like to tell
you a few words about my work.
The primary goal of my bachelor thesis was to develop/migrate a new
solution of OData service for Infinispan. New solution is needed, because
old solution was developed using odata4j library and development of this
library was kind of stopped. New solution of OData service is offered by
project Apache Olingo. In my work, I've created a servlet for Infinispan
cache using Apache Olingo library support for OData v4.
We can put, get, manage and most importantly also query JSON documents in
the cache. Querying is possible on basic key value or a property of JSON
document. Also, in queries, we can use operations AND, OR, EQUALS and
operations for reduction of a response list: SKIP and TOP.
Source code of my bachelor thesis is available at:
https://github.com/marib15/OlingoInfinispan-server
Tomas Sykora will review my code and push my solution to
https://github.com/infinispan/infinispan-odata-server master soon.
If community will have an interest, we can have a plan to continue in
development, so that server supports more operations... and also do
performance testing.
I know the solution is definitely not perfect but can definitely serve as
a baseline for future work, adjustments or adoption.
I am looking forward to hearing your responses!
Have a nice day :)
Ribarič
