So the FieldCache was removed from Solr 5. What is the implication of this? Should we move all facets to DocValues when we have high cardinality (lots of values) ? Are we adding it back?
Other ideas to improve performance? >From Mike M: FieldCache is gone (moved to a dedicated UninvertingReader in the miscmodule). This means when you intend to sort on a field, you should index that field using doc values, which is much faster and less heap consuming than FieldCache. -- Bill Bell billnb...@gmail.com cell 720-256-8076
