Adrien Grand updated LUCENE-4536:
---------------------------------
Attachment: LUCENE-4536.patch
New patch including Mike's suggestions:
- VERSION_LONG_ALIGNED renamed to VERSION_START,
- VERSION_CURRENT aliased to VERSION_BYTE_ALIGNED,
- added an assert that the sneaky direct reader impl can only be instantiated
if the stream has been produced with VERSION_START.
> Make PackedInts byte-aligned?

> PackedInts are more and more used to save/restore small arrays, but given
> that they are long-aligned, up to 63 bits are wasted per array. We should try
> to make PackedInts storage byte-aligned so that only 7 bits are wasted in the
> worst case.
