Fwd: Postgres-BDR 9.4 1.0 Released - Mailing list pgsql-announce

The HTML text formatting in Umair's original post is fatally flawed, with each
line of text overlapping the previous one by about 2/3 or more (as seen in
Thunderbird 38.8.0 and presumably also other clients.)  Here is a forward of the
same message converted to plain-text so that it is actually readable.

Bi-Directional Replication for PostgreSQL (Postgres-BDR, or BDR) is the first
open source multi-master replication system for PostgreSQL to reach full
production status, developed by 2ndQuadrant and assisted by a keen user
community. BDR is specifically designed for use in geographically distributed
clusters, using highly efficient asynchronous logical replication, supporting
anything from 2-48 nodes in a distributed database.


WHAT'S NEW?

Significant improvements related to stability and bug fixes have been made in
this release. The most important factors of this release are:

- Smoother handling of schema changes (DDL) statements allowing increased
operational stability and reduced maintenance.
- Various bug fixes for operational issues demonstrating high level of maturity
- Performance tuning, especially of global sequence handling
- Removal of the now deprecated UDR
- Extensive documentation improvements based upon user feedback

SUPPORT & RELEASE SCHEDULE

Postgres-BDR 9.4 1.0 will be supported until December 2019, when PostgreSQL 9.4
goes EOL. BDR continues to be developed and BDR9.6 will be released within 6
months. The BDR project has already delivered the majority of its code into
PostgreSQL core, though it will likely be about 2-3 more years before this
functionality is available in PostgreSQL core.


IS Postgres-BDR RIGHT FOR YOU?

BDR is well suited for databases where:

- Data is distributed globally
- Majority of data is written to from only one node at a time (For example, the
US node mostly writes changes to US customers, each branch office writes mostly
to branch-office-specific data, and so on.)
- There is a need for SELECTs over complete data set (lookups and consolidation)
- There are OLTP workloads with many smaller transactions
- Transactions mostly touching non overlapping sets of data
- There is partition and latency tolerance

However, this is not a comprehensive list and use cases for BDR can vary based
on database type and functionality.


In addition, BDR aids business continuity by providing increased availability
during network faults. Applications can be closer to the data and more
responsive for users, allowing for a much more satisfying end-user experience.


PROFESSIONAL SUPPORT FOR BDR


BDR is developed and supported by 2ndQuadrant. 2ndQuadrant provides professional
support for BDR, as well as consultation and training.  With our deep knowledge
of distributed databases, we will ensure that you are able to evaluate your use
case and applications and determine the most suitable product or solution.


BDR is also available in 2ndQuadrant Cloud, initially on AWS.
