Fully dynamic cache

[Marco Colombo <in...@gmail.com>]

Hi all,
I've a use case that requires a fully dynamic data structure.
What I'm trying to do is to do not have any java pojo class describing the
object stored in the cache, but full create the object based on user inputs.
I see that for these cases it is used the binary object, but all examples
that I've found starts from an already defined class.

It is possible to dynamically create an object and then performing sql
queries on it?
Is there any example?

Thanks!

Hi,

You can dynamically create and change binary objects with
BinaryObjectBuilder [1], but fields that you want to query must be specified
on node startup at least with QueryEntity [2], but altering internal query
tables at runtime is not possible for now.

Thanks!
