Andrew Mashenkov commented on IGNITE-8697:
------------------------------------------
Static fields looks very suspicous.
Is it possible, Sink object created with one class loader and then transferred
to thread with another classloader?
In that case static content will not be transfered with the object as it is not
belongs to object.
Also. Why we have static datastreamer instance here?
It is a closable object and it looks like can be reused by several threads. And
once streamer has been closed, it can be used.
