Yonik Seeley commented on SOLR-2583: ------------------------------------ bq. Perhaps it would be good to allow the user to override this, s.th. like sparse=yes/no/auto. Sounds good! I wonder what the memory cut-off should be for auto... 10% of maxDoc() or so? bq. a smallfloat option could help too? (1/4 the ram) Yep! > Make external scoring more efficient (ExternalFileField, FileFloatSource) > ------------------------------------------------------------------------- > > Key: SOLR-2583 > URL: https://issues.apache.org/jira/browse/SOLR-2583 > Project: Solr > Issue Type: Improvement > Components: search > Reporter: Martin Grotzke > Priority: Minor > Attachments: FileFloatSource.java.patch > > > External scoring eats much memory, depending on the number of documents in > the index. The ExternalFileField (used for external scoring) uses > FileFloatSource, where one FileFloatSource is created per external scoring > file. FileFloatSource creates a float array with the size of the number of > docs (this is also done if the file to load is not found). If there are much > less entries in the scoring file than there are number of docs in total the > big float array wastes much memory. > This could be optimized by using a map of doc -> score, so that the map > contains as many entries as there are scoring entries in the external file, > but not more. -- This message is automatically generated by JIRA.
