[jira] [Created] (LUCENE-10189) Optimize SortedSet/SortedNumeric
doc values writers for fields that are effectively single-valued
Adrien Grand created LUCENE-10189:
-------------------------------------
Summary: Optimize SortedSet/SortedNumeric doc values writers for fields that are effectively single-valued
Key: LUCENE-10189
URL: https://issues.apache.org/jira/browse/LUCENE-10189
Project: Lucene - Core
Issue Type: Wish
Reporter: Adrien Grand
I was wondering how much overhead multi-valued doc-value types have over their single-valued counterparts, so I hacked IndexTaxis to index all doc-value fields via Sorted(Set|Numeric)DocValuesField instead of (Sorted|Numeric)DocValuesField and flush times increased by 30%. It should be easy to automatically detect such cases in the doc values writers?
