-----------------------------------
Summary: DocValues impls should read all headers up-front instead
of per-directsource
Key: LUCENE-4539
URL: https://issues.apache.org/jira/browse/LUCENE-4539
Project: Lucene - Core
Issue Type: Bug
Components: core/index
Reporter: Robert Muir
Currently, when DocValues opens, it just opens files. it doesnt read codec
headers etc.
Instead we read these every single time a directsource opens.
I think it should work like PostingsReaders: e.g. the PackedInts impl would
read its versioning info and codec headers and creating a new Direct impl
should be a IndexInput.clone() + getDirectReaderNoHeader().
Today its much more costly.
