lucasbru opened a new pull request, #23346: URL: https://github.com/apache/kafka/pull/23346
Turning off the topology description plugin (unsetting `group.streams.topology.description.plugin.class`) or downgrading the broker below KIP-1331 both stop the broker from calling `deleteTopology` for groups that already have data recorded, since none of the code driving that cleanup runs anymore against that plugin instance. This is expected rather than a leak in the usual sense: the plugin's storage is external to the broker, so removing or downgrading the component managing its lifecycle naturally leaves that storage self-managed from then on. This adds a short section explaining that, and points operators who are removing the plugin or downgrading for good at cleaning up the plugin's backing storage themselves, plus a Troubleshooting entry for anyone who runs into leftover entries after doing either. No code changes. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
