Toke Eskildsen commented on SOLR-5894: -------------------------------------- [~alley]: Short answer: No concrete progress, sorry. We still use the 4.10 version in production, where it continue to work well for us. Longer answer: The primary update is that I am now a committer and that this is (naturally) one of the things I will pursue. But since I just became committer this week, I am _not_ going to touch this pile right away - I lned abunch of baby-steps first. > Speed up high-cardinality facets with sparse counters > ----------------------------------------------------- > > Key: SOLR-5894 > URL: https://issues.apache.org/jira/browse/SOLR-5894 > Project: Solr > Issue Type: Improvement > Components: SearchComponents - other > Affects Versions: 4.7.1 > Reporter: Toke Eskildsen > Priority: Minor > Labels: faceted-search, faceting, memory, performance > Attachments: author_7M_tags_1852_logged_queries_warmed.png, > SOLR-5894.patch, SOLR-5894.patch, SOLR-5894.patch, SOLR-5894.patch, > SOLR-5894.patch, SOLR-5894.patch, SOLR-5894.patch, SOLR-5894.patch, > SOLR-5894.patch, SOLR-5894_test.zip, SOLR-5894_test.zip, SOLR-5894_test.zip, > SOLR-5894_test.zip, SOLR-5894_test.zip, > sparse_2000000docs_fc_cutoff_20140403-145412.png, > sparse_5000000docs_20140331-151918_multi.png, > sparse_5000000docs_20140331-151918_single.png, > sparse_50510000docs_20140328-152807.png > > > Multiple performance enhancements to Solr String faceting. > * Sparse counters, switching the constant time overhead of extracting top-X > terms with time overhead linear to result set size > * Counter re-use for reduced garbage collection and lower per-call overhead > * Optional counter packing, trading speed for space > * Improved distribution count logic, greatly improving the performance of > distributed faceting > * In-segment threaded faceting > * Regexp based white- and black-listing of facet terms > * Heuristic faceting for large result sets > Currently implemented for Solr 4.10.
