Subject [jira] [Commented] (OAK-7686) Partial migration doesn't update Lucene indexing data
Date Tue, 07 Aug 2018 19:10:00 GMT

Vikas Saurabh commented on OAK-7686:
------------------------------------

bq. Because there's no LuceneIndexEditorProvider included there, some index definitions can't
be processed, producing an log message Missing index provider of type [lucene].
Since "lucene" indexes have {{async=XYZ}}, I think {{IndexUpdate}} \[0] instantiated with
async=null would care about them. The only reason I could think of {{IndexUpdate}} caring
about lucene indexes is if they have "sync" or "nrt" configured in "async" property.

A simple test for this is that the indexes that log the warning in description won't have
any index with simple {{async=["async"]}} (e.g. most likely /oak:index/lucene).

If that "guess" turns out to be true, the I think the right solution would be that {{IndexUpdate}}
shouldn't try to set "reindex=true" for updates it's trying for "nrt"/"sync".

About up/sidegrade indeed updating lucene indexes should be a separate issue imo.

> It seems that the LuceneIndexProvider is missing in the RepositorySidegrade index provider
list. As a result, for the partial migration, the lucene indexing data is not updated for
the copied content:
