Subject [jira] [Commented] (IGNITE-2703) .NET: Dynamically registered classes must use binary serialization if possible
Date Mon, 23 Jan 2017 12:18:26 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-2703?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15834366#comment-15834366
] 

Pavel Tupitsyn commented on IGNITE-2703:
----------------------------------------

Merged with ignite-2.0 and integrated with new {{MarshallerContext}} APIs. 

Most tests pass, the problem is with binary-only types (no classes at all) which are created
with {{BinaryBuilder}}. We should not even attempt to resolve type in such cases, but with
current logic we do, and this fails.

> At present we support dynamic class registration in .NET, but they are written using
deafult .NET mechanism. This is counterintuitive for users and not consistent with Java, where
such classes are written in binary form.
> Proposed implementation plan:
> 1) For each dynamically registered class we must understand whether it could be serialized
through binary or not. If not - print a warning and fallback to .NET.
> 2) Before writing a class we must ensure that it's [typeId -> name] pair is known
to the cluster. If not - write full class name instead of type ID. Java already do that.
> 3) Last, to support backward compatibility we must be able to fallback to current mode
with help of some boolean flag.
