Shai Erera updated LUCENE-5189: ------------------------------- Attachment: LUCENE-5189.patch Patch adds testStressMultiThreading and testUpdateOldSegments to ensure updating segments written with older format than "Lucene45" is not supported. > Numeric DocValues Updates > ------------------------- > > Key: LUCENE-5189 > URL: https://issues.apache.org/jira/browse/LUCENE-5189 > Project: Lucene - Core > Issue Type: New Feature > Components: core/index > Reporter: Shai Erera > Assignee: Shai Erera > Attachments: LUCENE-5189.patch, LUCENE-5189.patch, LUCENE-5189.patch, > LUCENE-5189.patch, LUCENE-5189.patch > > > In LUCENE-4258 we started to work on incremental field updates, however the > amount of changes are immense and hard to follow/consume. The reason is that > we targeted postings, stored fields, DV etc., all from the get go. > I'd like to start afresh here, with numeric-dv-field updates only. There are > a couple of reasons to that: > * NumericDV fields should be easier to update, if e.g. we write all the > values of all the documents in a segment for the updated field (similar to > how livedocs work, and previously norms). > * It's a fairly contained issue, attempting to handle just one data type to > update, yet requires many changes to core code which will also be useful for > updating other data types. > * It has value in and on itself, and we don't need to allow updating all the > data types in Lucene at once ... we can do that gradually. > I have some working patch already which I'll upload next, explaining the > changes. -- This message is automatically generated by JIRA.
