Subject FieldCache?
Date Tue, 06 Oct 2015 04:03:17 GMT
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
