Re: [druid-dev] any reason to still keep overlord as separate node?

[Gian Merlino <gi...@imply.io>]

Hi Prashant,

The only issue that I can think of is that in some (super large) clusters,
the coordinator and overlord can both be pretty demanding in terms of
memory and it helps for scalability to have them be separate. But this is
not the common case - most clusters are smaller or medium sized. So it
makes sense for the default to be combining them. I would support a patch
that changed the defaults and updated the docs accordingly.

Btw, since we are trying to migrate the dev mailing list to Apache, please
cross post this sort of thing with dev@druid.apache.org, or even only post
to that list.

I am one of those odd cases and agree with Gian on both accounts.
