Subject [jira] [Comment Edited] (IGNITE-2492) .NET: Peer assembly loading
Date Thu, 12 Jan 2017 12:14:52 GMT

------------------------------------------------------------------

Initial implementation proposal:
* Do not bother with unloading. Load assemblies in current AppDomain.
* Load assemblies by type name. If we get an object with unknown type, send peer loading request
with that type name.
* Use existing .NET mechanisms to send requests to other nodes (send a closure to all nodes
one by one)

There are two cases:
* Binarizable types. TypeId is known, but type can't be resolved in loaded assemblies.
* Serializable types. In this case we should handle assembly resolve event.

> Similar to peer class loading in Java, we can provide a possibility to load assemblies
on already started nodes, so that a node can execute jobs that are not present on other nodes.
> Considerations:
> * Can we unload assemblies after use to free memory? This requires a separate AppDomain,
can we work with that?
