Vladimir Ozerov updated IGNITE-2977:
------------------------------------
Labels: roadmap (was: )
> Implement generic ability to invoke Java code from non-Java platforms.
> ----------------------------------------------------------------------
>
> Key: IGNITE-2977
> URL: https://issues.apache.org/jira/browse/IGNITE-2977
> Project: Ignite
> Issue Type: Task
> Components: platforms
> Affects Versions: 1.5.0.final
> Reporter: Vladimir Ozerov
> Assignee: Vladimir Ozerov
> Priority: Critical
> Labels: roadmap
> Fix For: 1.7
>
>
> *Problem*
> Sometimes user could have mixed cluster when some nodes are running Java and
> some nodes running in platform mode. Obviously, in such deployments it is
> impossible to invoke non-Java code on Java nodes.
> It appears to be a serious limitation for users. For example, if cache nodes
> are Java-only, it is impossible to set remote filter from .NET.
> Known problematic places:
> - Remote filter in continuous query
> - Compute API
> - Scan Queries
> - Cache.invokes
> - "load cache" with non-null predicate
> - services
> - messaging remote listener
> - events remote query
> *Proposed solution*
> 1) Define two new types:
> {{JavaObject}} - encoded Java object; identified by a fully-qualified class
> name and a map of properties.
> {{JavaObjectFactory}} - factory object for more complex cases when some
> additional logic on Java side is required. Factory must support injections.
> 2) Implement corresponding wrappers in .NET/CPP and ensure they are unwrapped
> correctly.
> 3) Support individual features from the list above.
