Shai Erera updated LUCENE-5215: ------------------------------- Attachment: LUCENE-5215.patch Fixed some places which referenced Lucene45 (javadocs, comments etc.). Also made SR.readFieldInfos package-private, and added a deprecation comment to the new deprecated classes. I still didn't change PerField to use Long instead of Integer. Rob, if you think it's important, I'll do it, should be easy. Otherwise, I think it's ready to go in. I'll run some tests first. > Add support for FieldInfos generation > ------------------------------------- > > Key: LUCENE-5215 > URL: https://issues.apache.org/jira/browse/LUCENE-5215 > Project: Lucene - Core > Issue Type: New Feature > Components: core/index > Reporter: Shai Erera > Assignee: Shai Erera > Attachments: LUCENE-5215.patch, LUCENE-5215.patch, LUCENE-5215.patch, > LUCENE-5215.patch, LUCENE-5215.patch, LUCENE-5215.patch, LUCENE-5215.patch > > > In LUCENE-5189 we've identified few reasons to do that: > # If you want to update docs' values of field 'foo', where 'foo' exists in > the index, but not in a specific segment (sparse DV), we cannot allow that > and have to throw a late UOE. If we could rewrite FieldInfos (with > generation), this would be possible since we'd also write a new generation of > FIS. > # When we apply NDV updates, we call DVF.fieldsConsumer. Currently the > consumer isn't allowed to change FI.attributes because we cannot modify the > existing FIS. This is implicit however, and we silently ignore any modified > attributes. FieldInfos.gen will allow that too. > The idea is to add to SIPC fieldInfosGen, add to each FieldInfo a dvGen and > add support for FIS generation in FieldInfosFormat, SegReader etc., like we > now do for DocValues. I'll work on a patch. > Also on LUCENE-5189, Rob raised a concern about SegmentInfo.attributes that > have same limitation -- if a Codec modifies them, they are silently being > ignored, since we don't gen the .si files. I think we can easily solve that > by recording SI.attributes in SegmentInfos, so they are recorded per-commit. > But I think it should be handled in a separate issue. -- This message is automatically generated by JIRA.
