Shai Erera commented on LUCENE-4258:
------------------------------------
Sunny, there are many issues w/ the current patch. It doesn't handle many
corner cases and it's very complicated. I'm not saying the approach won't work,
just that the patch attempts to solve many update types in one go. For that
reason I opened LUCENE-5189 which laid out the ground for updating DocValues
fields. Even though it currently supports only NumericDocValues, we already
have a new issue LUCENE-5513 to add support for BinaryDV and I assume after
that we'll move to cover the rest of the DV types.
As for updating postings, I haven't yet given up on doing that, but it's more
complicated and we may do it in baby steps too (e.g. allow to only add tokens
for StringFields). But it will take time.
