In addition, right now only consumer > Fetcher had replace, but producer Sender does not have it actually. > So we should consider removing this logic in the consumer Fetcher's metrics > package. NOTE that this is a public API backward incompatible change. -- This message was sent by Atlassian Jira (v8.3.4#803005)
