Earwin Burrfoot commented on LUCENE-2471: ----------------------------------------- Bad link? The issue is closed already and no mentions of Directory in the patches. Immediate consumer, just as I said - is all bulk-merging code. I.e. - instead of loading norms to a byte array and then writing them out, you do, roughly: {code} IndexInput normFile = ...; IndexOutput newNormFile = ...; newNormFile.write(normFile, offset, length); {code} I looked at FSDir and refreshed my memory. copyTo is implemented with channels and transferTo, I think new method will look quite similar. > Supporting bulk copies in Directory > ----------------------------------- > > Key: LUCENE-2471 > URL: https://issues.apache.org/jira/browse/LUCENE-2471 > Project: Lucene - Java > Issue Type: Improvement > Reporter: Earwin Burrfoot > > A method can be added to IndexOutput that accepts IndexInput, and writes > bytes using it as a source. > This should be used for bulk-merge cases (offhand - norms, docstores?).
