--------------------------------------
Summary: Upgrade protocol-buffers version
Key: DRILL-6642
URL: https://issues.apache.org/jira/browse/DRILL-6642
Project: Apache Drill
Issue Type: Bug
Components: Tools, Build & Test
Affects Versions: 1.14.0
Reporter: Vitalii Diravka
Fix For: 1.15.0
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_):
