Hello, I'm not sure how to minimize the impact of performing a re-index (or new index creation), that will take 48 hours (using oak 1.4). I mean, I don't want to block other indexes update.
First, we have set the value of async as *fulltext-async* for the new index. I guess, that at least, all the indexes managed by the *async* lane <http://jackrabbit.apache.org/oak/docs/query/indexing.html#indexing-lane> will not be affected (please, confirm if I'm right). Then we try to minimize the impact on the fulltext-async lane. According to OAK-5553 <https://issues.apache.org/jira/browse/OAK-5553> there isn't much we can do while the indexing process is active for the new index, as the rest of indexes won't be updated. On the other hand, it seems that using the *reindex-async* flag (see OAK-1456 <https://issues.apache.org/jira/browse/OAK-1456>) could do the trick. I mean, setting reindex-async=true to the new index will allow other indexes (in the same lane) being updated while it is being populated? If that is true, we could create the index with that flag and then remove it. Regards.
