Adrien Grand updated LUCENE-9113: --------------------------------- Issue Type: Improvement (was: Bug) > Speed up merging doc values terms dictionaries > ---------------------------------------------- > > Key: LUCENE-9113 > URL: https://issues.apache.org/jira/browse/LUCENE-9113 > Project: Lucene - Core > Issue Type: Improvement > Reporter: Adrien Grand > Priority: Minor > > The default {{DocValuesConsumer#mergeSortedField}} and > {{DocValuesConsumer#mergeSortedSetField}} implementations create a merged > view of the doc values producers to merge. Unfortunately, it doesn't override > {{termsEnum()}}, whose default implementation of {{next()}} increments the > ordinal and calls {{lookupOrd()}} to retrieve the term. Currently, > {{lookupOrd()}} doesn't take advantage of its current position, and would > seek to the block start and then call {{next()}} up to 16 times to go to the > desired term. While there are discussions to optimize lookups to take > advantage of the current ord (LUCENE-8836), it shouldn't be required for > merging to be efficient and we should instead make {{next()}} call {{next()}} > on its sub enums. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
