2ndQuadrant is proud to announce the release of version 1.2.1 of Barman, Backup and Recovery Manager for PostgreSQL.

This minor release introduces support for bandwidth limitation through the "bandwidth_limit" option. This option allows administrators to set the maximum number of kilobytes per second for backup and recovery operations. Different bandwidth caps can be set for different servers.

More control on bandwidth limitations can be achieved through the "tablespace_bandwidth_limit" option that allows to cap the bandwidth usage for one or more specific PostgreSQL tablespaces.

By default, no bandwidth limitation is enforced, making Barman 1.2.1 fully compatible with configuration files from previous versions. This set of features gives administrators finer control on regular backup activities, reducing the impact of these operations on live systems.

Minor bugs have also been fixed.

Release Notes

• Added the "bandwidth_limit" global/server option which allows to limit the I/O bandwidth (in KBPS) for backup and recovery operations
• Added the "tablespace_bandwidth_limit" global/server option which allows to limit the I/O bandwidth (in KBPS) for backup and recovery operations on a per tablespace basis
• Added /etc/barman/barman.conf as default location
• Bug fix: avoid triggering the minimum_redundancy check on FAILED backups (thanks to Jérôme Vanandruel)

About Barman

Barman (Backup and Recovery Manager) is an open source administration tool for disaster recovery of PostgreSQL servers written in Python. It allows your organisation to perform remote backups of multiple servers in business critical environments and help DBAs during the recovery phase. Barman's most requested features include backup catalogues, retention policies, remote recovery, archiving and compression of WAL files and backups.

Built on top of PostgreSQL's robust and reliable Point-In-Time-Recovery technology, Barman allows database administrators to manage the backup and recovery phases of several PostgreSQL database servers from a centralised location, using an intuitive command interface. Barman is distributed under GNU GPL 3.

2ndQuadrant has launched a ‘carrier-grade’ support service for companies who require absolute mission-critical incident protection.

The company has decided to offer this level of service commitment to support the rapidly growing adoption of PostgreSQL by enterprises requiring the highest level of support services.

This new service, branded Platinum Production Support, provides the additional reassurance of a guaranteed 15-minute (human) response time, 4-hour workaround, and a fix within 24 hours for PostgreSQL production databases. With 24/7 coverage included too.

2ndQuadrant has an excellent track record of recovering databases for companies of all sizes, having provided 24/7 production support for over 8 years. Simon Riggs, CTO of 2ndQuadrant, said, “More of our major clients from financial, telecoms and internet-based sectors are increasingly requiring extraordinary levels of up-time to avoid the potentially significant costs of downtime. With the rise in PostgreSQL databases at the heart of these mission-critical operations, we've launched this new service to ensure that organisations have the best support available, and equally to provide reassurance in their choice of database. The Platinum service complements our popular Gold service, providing clients—where every minute of downtime counts—with the reassurance they need.”

PostgreSQL is becoming a default choice for many leading corporations and public sector organisations, who can see the value in open source products and the benefits of reducing the costs of fee-based database licences. 2ndQuadrant’s launch of this level of support heralds new expectations of PostgreSQL, and helps dismiss the fears amongst the sceptics that an open source database might be a higher-risk choice.

Platinum Production Support is available now from 2ndQuadrant. Find out more at http://2ndQuadrant.com/support/

The first beta release of PostgreSQL 9.3, the latest version of the world's best open source database, is now available. This beta contains previews of all of the features which will be available in version 9.3, and is ready for testing by the worldwide PostgreSQL community. Please download, test, and report what you find.

Major Features

The major features available for testing in this beta include:

• Writeable Foreign Tables, enabling pushing data to other databases
• pgsql_fdw driver for federation of PostgreSQL databases
• Automatically updatable VIEWs
• MATERIALIZED VIEW declaration
• LATERAL JOINs
• Additional JSON constructor and extractor functions
• Indexed regular expression search
• Disk page checksums to detect filesystem failures

In 9.3, PostgreSQL has greatly reduced its requirement for SysV shared memory, changing to mmap(). This allows easier installation and configuration of PostgreSQL, but means that we need our users to rigorously test and ensure that no memory management issues have been introduced by the change. We also request that users spend extra time testing the improvements to Foreign Key locks.

Additional Features

Additional features included in this release are:

• Fast failover to replicas for high availability
• Streaming-only remastering of replicas
• Performance and locking improvements for Foreign Key locks
• Parallel pg_dump for faster backups
• Directories for configuration files
• pg_isready database connection checker
• COPY FREEZE for reduced IO bulk loading
• User-defined background workers for automating database tasks
• Recursive view declaration
• lock_timeout directive

For a full listing of the features in version 9.3 Beta, please see the release notes. Additional descriptions and notes on the new features are available on the 9.3 Features Wiki Page.

The AXLE Consortium are pleased to announce the start of the AXLE database research project, funded by European Union under FP7 grant. axleproject.eu

The objectives of the AXLE project are to greatly improve the speed and quality of decision making on real-world data sets. AXLE aims to make these improvements generally available through high quality open source implementations via the PostgreSQL database and Orange data visualisation and data mining tools.

AXLE project members are

• Barcelona Supercomputing Centre (SC)
• Portavita
• University of Manchester
• University of Ljubljana coordinated by 2ndQuadrant

Areas of research will include data analysis algorithms for Big Data, advanced hardware architectures, data visualisation and security. Target environments are real-world data in the 10-100 TB range.

"Real world data needs good security too, so we'll be making sure we have high grade security that works well even with high performance requirements", says Simon Riggs, CTO of 2ndQuadrant and Principal Investigator for the AXLE project. "We're very happy that the European Union has recognised the potential of the PostgreSQL database to provide effective database analytics for a broad range of business, research and public services."

First deliverables from the project will be submitted to PostgreSQL version 9.4, available in 2014 and will continue in later releases.

Project updates will be available regularly here as work continues.

Sprout is a project dedicated to a nested key-value pair programming language native to the Entity Attribute Value database model. Its environment is a Relational Database Management System, specifically Postgres 9. It is implemented with Procedural SQL and employs a key-value translator vernacular to EAV data model. The model provides storage of objects, object metadata definitions and program code. Sprout executes requests via SQL client interface and returns objects of various types. It has characteristics of a column-oriented database.
