Mikhail Khludnev commented on SOLR-3076: ---------------------------------------- [~thetaphi] what is the reason of delaying this functionality, if we can deliver it now with the following configuration "footprint"? {code:xml} <query> <cache name="cachingWrapperFilterCache" class="solr.search.LRUCache"> </query> <queryParser name="parent" class="join.BlockJoinParentQParserPlugin"> <!-- if you omit this BJQ will perform "suboptimal", thought functionally complete, also it annoyingly warns --> <str name="parent-filter-cache">cachingWrapperFilterCache</str> </queryParser> {code} Broken Solr on segments seems crucial to me too. I suppose that refactoring will take even much time than this modest piece of functionality. I feel it's really challenging from design perspective e.g. can CachingWrapperFilter flip between dense and sparse sets already? shouldn't it use off-heap memory like in LUCENE-5052 rather than pollute the heap? whether filters behavior is defined in index time or can be requested ad-hoc? etc Once again, what about going ahead with small configuration footprint, without diverging join queries. thanks > Solr(Cloud) should support block joins > -------------------------------------- > > Key: SOLR-3076 > URL: https://issues.apache.org/jira/browse/SOLR-3076 > Project: Solr > Issue Type: New Feature > Reporter: Grant Ingersoll > Fix For: 4.5, 5.0 > > Attachments: 27M-singlesegment-histogram.png, 27M-singlesegment.png, > bjq-vs-filters-backward-disi.patch, bjq-vs-filters-illegal-state.patch, > child-bjqparser.patch, dih-3076.patch, dih-config.xml, > parent-bjq-qparser.patch, parent-bjq-qparser.patch, Screen Shot 2012-07-17 at > 1.12.11 AM.png, SOLR-3076-childDocs.patch, SOLR-3076.patch, SOLR-3076.patch, > SOLR-3076.patch, SOLR-3076.patch, SOLR-3076.patch, SOLR-3076.patch, > SOLR-3076.patch, SOLR-3076.patch, SOLR-3076.patch, SOLR-3076.patch, > SOLR-3076.patch, SOLR-3076.patch, SOLR-3076.patch, > SOLR-7036-childDocs-solr-fork-trunk-patched, > solrconf-bjq-erschema-snippet.xml, solrconfig.xml.patch, > tochild-bjq-filtered-search-fix.patch > > > Lucene has the ability to do block joins, we should add it to Solr. -- This message is automatically generated by JIRA.
