Robert Muir commented on LUCENE-4547:
-------------------------------------
If you don't want like FieldCache in ES, then use something else.
Its really broken that things like grouping and faceting are coded to a
separate API. This makes DV unsuccessful. If we arent going to fix DocValues
and Faceting APIs then perhaps we shoudl consider removing DocValues completely
from lucene.
Please try to give the branch some time. I committed some work last night very
late and got tired and went to sleep. Its not "ready" and i'm not threatening
to commit to trunk.
I created this branch to develop publicly. I don't have to do that: I can
develop privately instead and not deal with complaints about my every step
before I even say things are ready. I just thought it would make it easier for
other people to help.

> I tried to write a test to sanity check LUCENE-4536 (first running against
> svn revision 1406416, before the change).
> But i found docvalues is already broken here for large indexes that have a
> PackedLongDocValues field:
> {code}
> final int numDocs = 500000000;
> for (int i = 0; i < numDocs; ++i) {
> if (i == 0) {
> field.setLongValue(0L); // force > 32bit deltas
> } else {
> field.setLongValue(1<<33L);
> }
> w.addDocument(doc);
> }
> w.forceMerge(1);
> w.close();
> dir.close(); // checkindex
> {code}
