    Hi hackers.   Ref: http://wiki.postgresql.org/wiki/BDR_Project   Is 
implementing main BDR features into core Postgres a probable objective to 
version 9.4?   Thanks.   --

No.

No BDR feature has been proposed for core PostgreSQL so far.  Also, this
feature builds on top of the logical replication features, which are
themselves questionable for 9.4.

Not fully. We hope to integrate some of the building blocks into
postgres soon, so we can reduce the size of the diff. Then the plan is
to iteratively (continue) to submit features required.

Well, that's not really true. For one, changeset extraction actually is
part of the effort, which surely has been submitted. There also have
been some further submissions which help build robust replication
solutions. One or two of those might be possible to get into 9.4 (they
have been in the last CF...)

Greetings,

I've not updated hackers recently on this point, so thanks for asking
the question. This was discussed in the ending keynote of the PG
Europe conference, but I appreciate that's not the same thing as
saying it here.

The plan is

* submit the core logical replication technology for 9.4
* submit online upgrade as a feature for 9.5, allowing upgrades from 9.4+
* submit full BDR features for 9.6

BDR code will be released as a separate open source project until/if
core accepts/modifies that. There's lots of work and discussion to be
had yet, so the above plan is a reasonable schedule for achieving
change allowing input from all. Design to full feature submission
would be 4.5 years, plus we expect the features to mature/extend after
that, so there's no rush, just steady movement.

No attempts to publicise that as yet, but if all goes well we expect
to do that once 9.4 is released.
