Summary: Let DatasetSplitter approximate no. of class values by no. of terms Key: LUCENE-7591 URL: https://issues.apache.org/jira/browse/LUCENE-7591 Project: Lucene - Core Issue Type: Improvement Components: modules/classification Reporter: Tommaso Teofili Assignee: Tommaso Teofili Fix For: master (7.0) Currently {{DatasetSplitter}} throws an exception if it's not possible to find {{SortedDocValues}} or {{SortedSetDocValues}} on the class field as it wouldn't be possible to correctly split the indexes in a balanced way. As a fallback we could instead use the no. of terms per leaf reader as an approximate count (upper bound) to the no. of classes. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
