Robert Muir commented on LUCENE-5911: ------------------------------------- David: you are right. This caching is unnecessary in my opinion. Instead if the optional freeze() method is supposed to prepare internal structures for querying, I would have freeze() just prebuild, populate an ArrayList<NumericDocValues> (indexed by field number), by calling getNormValues() for each one. If you don't call freeze, this list is null, and it just returns a new one each time: not worth caching or anything for that case. > Make MemoryIndex thread-safe for queries > ---------------------------------------- > > Key: LUCENE-5911 > URL: https://issues.apache.org/jira/browse/LUCENE-5911 > Project: Lucene - Core > Issue Type: Improvement > Reporter: Alan Woodward > Assignee: Alan Woodward > Priority: Minor > Fix For: 5.0, Trunk > > Attachments: LUCENE-5911.patch, LUCENE-5911.patch > > > We want to be able to run multiple queries at once over a MemoryIndex in > luwak (see > https://github.com/flaxsearch/luwak/commit/49a8fba5764020c2f0e4dc29d80d93abb0231191), > but this isn't possible with the current implementation. However, looking > at the code, it seems that it would be relatively simple to make MemoryIndex > thread-safe for reads/queries. -- 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
