Michael McCandless updated LUCENE-2321:
---------------------------------------
Attachment: LUCENE-2321.patch
First cut -- it has some limitations though:
* Cannot handle termsIndexInterval yet (forces this to 1)
* Loads all term data as a single byte[] -- this may be a problem, eg it
means your total bytes for indexed terms cannot exceed 2.1B; it also may fail
to allocate due to memory fragmentation on 32 bit JREs. So I think we have to
make this paged.
Also found & fixed some small bugs in packed ints.
> use packed ints for the terms dict index

> Terms dict index needs to store large RAM resident arrays of ints, but,
> because their size is bound & variable (depending on the segment/docs), we
> should used packed ints for them.
