Pritesh Maker commented on DRILL-6642:
--------------------------------------

[~vitalii] are there any backward compatibility considerations with this upgrade? Anything specific from a testing/ QA perspective to watch out for?

> Currently Drill uses 2.5.0 {{protocol-buffers}} version.
>  The last version is 3.6.0 in maven repo: [https://mvnrepository.com/artifact/com.google.protobuf/protobuf-java]
> The new version has a lot of useful enhancements, which can be used in Drill.
>  One of them is using {{UNRECOGNIZED Enum NullValue}}, which can help to handle them in place of null values for {{ProtocolMessageEnum}} - DRILL-6639. 
>  Looks like the NullValue can be used instead of null returned from {{valueOf()}} (_or {{forNumber()}}, since {{valueOf()}} is deprecated in the newer protobuf version_):
