(sorry for the mistake of my side which made this unterminated message to be sent, let me redo)
Hello, I am trying to upgrade from Solr 8.11.2 to 9.6.0, my collections are relying on docValuesFormat="Direct" for some of their attributes, and if I leave them "as is", then I get the following error in Solr Server's logs: 2024-03-11 11:43:47.120 ERROR (commitScheduler-84-thread-1) [c:rts-metricslist-def-v2 s:shard1 r:core_node2 x:rts-metricslist-def-v2_shard1_replica_n1 t:] o.a.s.u.CommitTracker auto commit error... => org.apache.solr.common.SolrException: Error opening new searcher at org.apache.solr.core.SolrCore.openNewSearcher(SolrCore.java:2467) org.apache.solr.common.SolrException: Error opening new searcher at org.apache.solr.core.SolrCore.openNewSearcher(SolrCore.java:2467) ~[?:?] at org.apache.solr.core.SolrCore.getSearcher(SolrCore.java:2600) ~[?:?] at org.apache.solr.update.DirectUpdateHandler2.commit(DirectUpdateHandler2.java:775) ~[?:?] at org.apache.solr.update.CommitTracker.run(CommitTracker.java:279) ~[?:?] at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:539) ~[?:?] at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) ~[?:?] at java.base/java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:304) ~[?:?] at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1136) ~[?:?] at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635) ~[?:?] at java.base/java.lang.Thread.run(Thread.java:857) [?:?] Caused by: java.lang.IllegalArgumentException: An SPI class of type org.apache.lucene.codecs.DocValuesFormat with name 'Direct' does not exist.

Is there anybody using docValuesFormat="Direct" with Solr 9 ? Note: I tried removing this attribute from my collections's definition, but performance (especially on update) are quite bad vs what I had with Solr 8.11.2 with this attribute. I also tried running my collections with Solr 9.6.0 while setting luceneMatchVersion to 8.11.2 and removing this attribute, the performance issue is a bit less concerning but still updates max time can be very slow vs. what I had with actual 8.11.2 with docValuesFormat="Direct". I would like to measure the performances of my application with Solr 9.6.0 and with docValuesFormat="Direct" for same attributes as I had in my collections as when I was running with 8.11.2, but I need help to idenfity the missing JAR that will allow using this "Direct" docValuesFormat... anyone having a clue ?
