jiangphcn commented on issue #1186: [WIP] Clustered purge mixed cluster upgrade URL: https://github.com/apache/couchdb/pull/1186#issuecomment-370790664 Thanks Paul @davisp for your reply. I understand. For completeness, we need to consider downgrade when there is purge request between pre-CP and CP. However, only with CP build, the clustered purge API is available. Before that, there is less possibility to have purge request. So downgrade may not be effort we should focus on. Regarding the second point "unused/idle indexes after upgrade", as you know, we have two methods to trigger init/update of secondary index, search index and geo index. - issue search request and trigger update of index - use `ken` or similar approach to automatically trigger init/update of index If there is unused/idle index, what about leveraging `ken` or similar approach to trigger index o run an initial step? Thus, if there is update on database document, ken will trigger init/update of index, thus the local purge document will be created so that purge requests will not be compacted before a index see them.
