[jira] [Commented] (CASSANDRA-17166) Switch to Jackson for config property definition to allow private fields and getter/setter support

["David Capwell (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-17166?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17446640#comment-17446640 ] 

David Capwell commented on CASSANDRA-17166:
-------------------------------------------

Here is a quick POC: https://github.com/apache/cassandra/pull/1335. Ideally it would be good to go through ObjectMapper and have the SnakeYaml backend (need to add jar), this would give us access to the full set of Jackson object mapping capabilities (such as constructor properties).

Here is the CI results to see what breaks: https://app.circleci.com/pipelines/github/dcapwell/cassandra?branch=CASSANDRA-17166

> SnakeYaml is rather limited in the “object mapping” layer, which forces our internal code to match specific patterns (all fields public and camel case); we can remove this restriction by leveraging Jackson for property lookup, and leaving the YAML handling to SnakeYAML
