Subject [jira] [Commented] (LUCENE-2621) Extend Codec to handle also stored fields and term vectors
Date Mon, 07 Nov 2011 20:28:52 GMT


Robert Muir commented on LUCENE-2621:

OK I think the stored fields are all cleaned up in the lucene2621 branch: the issues Andrzej
when trying to extend it should no longer be an issue: fdx/fdt are no longer in IndexFileNames
(but codec-private),
codecs can override how merging happens for stored fields (the default is just the obvious
the indexinput/output "raw" methods for bulk merging are removed from the abstract API and
inside DefaultFieldsReader/Writer, DefaultFieldsWriter overrides merge() and uses bulk optimisations

when the paired-up reader is also a DefaultFieldsReader

Before merging to trunk, i think we need a SimpleText stored fields implementation to ensure
everything is ok... 
I'll try to do this next.

> Currently Codec API handles only writing/reading of term-related data, while stored fields
data and term frequency vector data writing/reading is handled elsewhere.
> I propose to extend the Codec API to handle this data as well.
