Hi team!
I need to ask for your help.
It's connected to the OData endpoint.
(https://issues.jboss.org/browse/ISPN-2109) I was thinking about the design
etc. and it would be nice to map OData queries to Infinispan queries so clients
can get their results based on particular query.
You know, there is basically not much to do with only schema-less key-value
store. Like exposing only values to clients based on their key requests does
not fully use OData capabilities.
So I was thinking about something like that...
>From any client you are sending JSON object (for example a Book, with
>variables: title, author, description) to OData service and would like to
>store query-able Book Object value into the cache "under" some key.
So you go: JSON --> to query-able Book.class Object --> cache.put("key",
bookFromJson);
Then in pseudo query: get-me-books-filter-description-contains-"great IT
book"-top-N-results --> issue query on cache, get results --> transform
returned Books.class into JSON, return to client
My question is:
How to transform JSON input, which is in most cases simple String build
according to JSON rules, into object, which is query-able and can be put into
the cache.
The thing is that you usually have java class:
@Indexed
Book {
@Filed String title;
@Filed String author;
etc. etc.
I simply don't know how to create an object ready for queries, or even
annotated class and instantiate it for further put into the cache.
I'm discovering this, recently: http://www.jboss.org/javassist
Or can you see there any other, maybe totally different, approach how to do it?
THANK YOU very much for any input!
I'm stuck on this right now... that's why I'm asking for a help.
Have a nice day all!
Tomas
