Robert Muir commented on SOLR-2583: ----------------------------------- Are you sure real floats are actually needed? Why not use compactbytearray with smallfloat encoding? it would also good to measure performance... doesn't a hashmap have to box *per-docid* into an Integer for lookup? > 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, patch.txt > > > 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.
