Re: peer deployment for lambdas
Dmitriy,
Lambdas deployment should work - we have tests for it.
Can you make sure you don't wrap lambda in anything available from standard
classpath? Like here - org.apache.ignite.stream.StreamTransformer#from().
This may not work and you will need to manually set deployment class.

I don't really like this solution. Every time you add a step like that, you
add a possibility for user to skip it and then 100 forum questions follow.
Can we do it automatically? Why not call deployClass ourselves in the
StreamTransformer.from(...) method?

DataStreamer has deployClass() property for cases when automatic resolution
is impossible

Ouch...
Is there any way to make it work? For example, can we do explicit class
deployment directly from StreamTrasformer.from(...) method?
