I just don’t know what “AI id feature” is 
As i suppose 4.1.1-EE (released recently) has broken indexer; see my post 4.1.0-EE vs 4.1.1-EE: indexer too slow
So, 4.1.1-EE really fixes https://issues.couchbase.com/browse/MB-17231, but introduces (probably) broken indexer. And, of course, there is no info about (possible ?) 4.1.1-CE release.
