The documentation that you are referring to is actually the [KnowledgeBase article][1] for "Known issues for Sitecore 8.2", and the statement that you quoted is actually an entry that lists this as a known issue for the Publishing Service in Sitecore 8.2:

> The Publishing Service does not maintain the descendant table by default.

You should reach out to Sitecore Support for this issue. Since there is no reference number included with the entry, you should link them to the KB article and mention the quoted text to see if they can provide you with a workaround/patch.
