Subject Stored fields access
Date Thu, 25 Feb 2010 12:52:13 GMT
I'm thinking, should Lucene introduce new interface to read stored
document fields?

Current 'Document document(int n)' mechanism is barely usable due to
overhead involved. While I believe underlying index structure works
pretty fast (if it fits in memory, as is the case for most
performance-concerned installations), there's no adequate access to it
and people are forced to introduce contraptions like LinkedIn's
payload-assisted luceneId<->appId mapping or similar caches we employ.

What I am thinking about is something along the lines of existing
iterators like TermDocs/TermPositions. Iterate over docs, then iterate
over fields stored for each, extract data, ???, profit.
Comments?
