We should deprecate the configs, give them a default of > JsonConverter (which is also kind of nice since it results in human-readable > data in the internal topics), and then ultimately remove them in the next > major version. > These are all public APIs so this will need a small KIP before we can make > the change. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
