Subject Re: Replacing NodeFilter functionality with label approach
Date Mon, 05 Aug 2019 12:40:52 GMT
Hello, Pavel.

I think we shouldn't reduce flexibility of NodeFilter.
So, I am -1 to remove it in Ignite 3.

Instead, Ignite can provide NodeAttributeFilter implementation of NodeFilter.
Seems, it will resolve all described issues.
