Yonik Seeley commented on LUCENE-4575: -------------------------------------- bq. I don't think though that it's trivial to support. Currently the user can pass any Map, but IndexReader returns in practice a HashMap (DataInput.readStringStringMap initializes a HashMap). If a user cared about order, then they would pass a LinkedHashMap. Then the only thing that would need to change is DataInput.readStringStringMap: s/HashMap/LinkedHashMap. bq. it's not really related to how the map is set. It is... if you make a copy of the map and we want to preserve order, it's new LinkedHashMap instead of HashMap. It's a minor enough point I don't think it does deserve it's own issue. I don't personally care about preserving order - but I did think it was worth at least bringing up. > Allow IndexWriter to commit, even just commitData > ------------------------------------------------- > > Key: LUCENE-4575 > URL: https://issues.apache.org/jira/browse/LUCENE-4575 > Project: Lucene - Core > Issue Type: Improvement > Components: core/index > Reporter: Shai Erera > Priority: Minor > Attachments: LUCENE-4575.patch > > > Spinoff from here > http://lucene.472066.n3.nabble.com/commit-with-only-commitData-td4022155.html. > In some cases, it is valuable to be able to commit changes to the index, even > if the changes are just commitData. Such data is sometimes used by > applications to register in the index some global application > information/state. > The proposal is: > * Add a setCommitData() API and separate it from commit() and prepareCommit() > (simplify their API) > * When that API is called, flip on the dirty/changes bit, so that this gets > committed even if no other changes were made to the index. > I will work on a patch a post. -- This message is automatically generated by JIRA.
