Benjamin Mahler created MESOS-9896:
--------------------------------------
Summary: Consider using protobuf provided json conversion
facilities rather than custom ones.
Key: MESOS-9896
URL: https://issues.apache.org/jira/browse/MESOS-9896
Project: Mesos
Issue Type: Task
Components: stout
Reporter: Benjamin Mahler
Currently, stout provides custom JSON to protobuf conversion facilities, some
of which use protobuf reflection.
When upgrading protobuf to 3.7.x in MESOS-9755, we found that the v0 /state
response of the master slowed down, and it appears to be due to a performance
regression in the protobuf reflection code.
We should file an issue with protobuf, but we should also look into using the
json conversion code that protobuf provides to see if that can help avoid the
regression.
