Yes, we are.  There are some schedule changes to the Developer Meeting
being proposed, and I will need to schedule around that.  But the plan
is to have one.

Expect this meeting to be on Wednesday of pgCon week, rather than
Tuesday as in the past.  Final confirmation of the new schedule in 1 week.

There will be a closed developer meeting on Tuesday morning.  Instead
of spending a whole day doing a closed developer meeting as we have in
the past, we will instead have a half-day closed session and then
switch to an unconference format for Tuesday afternoon and all of
Wednesday.  So, depending on your point of view, the developer meeting
is either half as long as before (half a day instead of all day) or
twice as long as before (two days instead of one day).

I suggest that it would be best to integrate the cluster summit into
the unconference time.  In the unconference format, the schedule is
not determined in advance; rather, it is determined at the event.  We
will ask those attending the unconference what topics they wish to
talk about.  Then, we will ask those in attendance which talks they
wish to attend.  The talks that are popular will be assigned a room
from among the three allocated to the unconference.  The talks that
few or no attendees wish to attend won't be assigned a room, and thus
won't happen.

I think this format offers several advantages.  On the one hand, I
expect the unconference to include a large number of the senior
PostgreSQL developers, and so clustering-related topics which are of
interest may attract the attention of senior hackers who have not gone
to the cluster summit in the past.  On the other hand, both the
developer meeting and the cluster summit have the problem that time is
sometimes allocated to topics in which there is not much interest,
because the organizers do not want to say "no" to anyone.  The
unconference format will help us to solve this problem by asking
attendees to vote, not just on the clustering topics, but on all the
topics.  People will not need to decide between attending the cluster
summit and skipping it; they can decide to attend sessions on the
specific topics they want to hear about.

Ultimately, I think it is very important to integrate "cluster
hacking" back into "PostgreSQL hacking".   This mailing list
(pgsql-cluster-hackers) is all but dead. Meanwhile, interesting
cluster work is being done on pgsql-hackers (see commit
cb1ca4d800621dcae67ca6c799006de99fa4f0a5 and
https://commitfest.postgresql.org/4/161/ among other examples).  We
need to stop thinking of clustering as something that is going to
happen only outside of PostgreSQL core and begin thinking of it as an
integral part of the work that we need to do to make PostgreSQL
successful.

Agreed.  See my sharding presentation for an overview of a possible
approach:

Thanks for the input. I will talk to NTT people and reply back if it
is allowed.

Well I think it depends on the definition of "cluster hacking". For
example, the most common reason people want to use pgpool-II are query
dispatching, automatic fail over and read query load balancing (plus
connection pooling sometimes). That means without these PostgreSQL
will not succeed in the real world IMO. But most PostgreSQL developers
tend to think that they are not part of "cluster hacking", and they
seem to want to avoid integrating them into PostgreSQL core.

This is the current plan.  The "Cluster Track" will be on Tuesday
afternoon and Wednesday, as part of the general Developer Unconference.

Ok, there will be no closed cluster summit this year.

I'm a little bit confused.

So In my understanding, there's no pre-reserved tracks in the
unconference for particular topic since people can vote "no" to the if
they have no interest in the cluster topics.

Or a room will be reserved for cluster topics only in Wednesday
afternoon?

Since last year's Cluster Summit attracted many participants (27 in RSVP list,
and much more in actual), we can expect same in this year.
In general, unconference topics will be selected on site. But if many people
express intent to participate it previously, a track dedicated to cluster
might be pre-reserved.
How do you think about, Josh?
Anyway, NTT, which will co-sponser unconference sessions this year, has already
planned
the Cluster Summit 2015 as usual.
Josh is kindly doing the organizing work.

Yes, my plan is to set up a wiki page where people can suggest topics in
advance.  Particularly, we'll want to coordinate for items which include
meetings of dev teams, such as the Postgres-XC development team.

Stay tuned.
