That's correct. It adds some latency to an NRT refresh, and some heap used to hold the ordinal mappings. > ii) During indexing, we are providing facet ordinals in each doc > and I think it will be useful in search side, to calculate facet counts > only for matching docs. otherwise, it carries any other benefits? Well, compared to the taxonomy facets, SSDV facets don't require a separate index. But they add latency/heap usage, and they cannot do hierarchical facets yet (though this could be fixed if someone just built it). > iii) Is SortedSetDocValuesReaderState thread-safe (ie) multiple > threads can call this method concurrently? Yes.
