RE: [cdt-dev] Indexer conf call?


The whole reason that the remote indexing thing came about is because we
have multiple customers, internally and externally, who want remote
indexing.  We have been bending over backwards for over six months to
engage you and the other committers on the discussion on the design and
haven't even commited a single line of code to the repository related to it
because we care about everyone else's opinions and needs.  I would hardly
say that we're acting on a whim.  I realize you don't like the design, but
we're following the process every step of the way.

At any rate, I'm working on getting setup to do some benchmarking on the
indexer over SMB shares, so I hope to get you some hard numbers on that
scenario soon.  I had been hoping to get those numbers in time for the call
on Thursday but it's been taking time getting access to an appropriate

I'm not totally sure what you guys are talking about. If you are talking
about the DAO thing, I don't consider that an API of the CDT. In fact I'd
rather people not know about it. It is a hack to allow the IBM to tear
the CDT at their whim while adding complexity to an already too complex
architecture. No one else will benefit from it. Did I mention I really
like this thing? ;) Until someone shows me the real costs, I will continue
to believe that indexing locally and accessing the files over the wire is
the correct architecture, especially now that the CDT never parses an
unchanged file more than once.

So as such, the DAO interface can be changed whenever.
