Barman 1.4.0 released

Mon, 01/26/2015 - 01:00

26 January 2015: 2ndQuadrant is proud to announce the release of version 1.4.0 of Barman, Backup and Recovery Manager for PostgreSQL.

This major release features file-level incremental backup, a kind of full periodic backup which saves only data changes from the latest full backup available in the catalogue for a specific PostgreSQL server. Depending on the context and the database workload, the data deduplication ratio might easily reach 50-70% per full backup, leading to significant reductions in both backup time and disk space.

PostgreSQL 9.4 users will transparently benefit from the integration of Barman with "pg_stat_archiver" view. In particular, any continuous archiving problem will be immediately spotted by the "barman check" command directly on the source.

Management of WAL files has been improved, by optimising the calculation of WAL statistics, tying archiving with backup and by distinctively managing WAL trashing for exclusive and concurrent backups.

Relevant efforts in unit testing have made the code more robust. Minor bugs have also been fixed.

Many thanks for funding towards the development of this release go to BIJ12 (www.bij12.nl), Jobrapido (www.jobrapido.com), Navionics (www.navionics.com), Sovon Vogelonderzoek Nederland (www.sovon.nl), and Subito.it (www.subito.it).

For a complete list of changes, see the "Release Notes" section below.

Incremental backup

Incremental backup is a kind of full periodic backup which saves only data changes from the latest full backup available in the catalogue for a specific PostgreSQL server. The main goals of incremental backup in Barman are:

  • Reduce the time taken for the full backup process
  • Reduce the disk space occupied by several periodic backups (data deduplication)

This feature heavily relies on "rysnc" and hard links, which must be therefore supported by both the underlying operating system and the file system where the backup data resides.

The main concept is that two periodic base backups will share those files that have not changed, leading to relevant savings in disk usage. This is particularly true of VLDB contexts and, more in general, of those databases containing a high percentage of read-only historical tables. Barman implements incremental backup through a global/server option, called "reuse_backup", that transparently manages the "barman backup" command. Behaviour can also be changed at runtime through the "--reuse-backup" runtime option for the "barman backup" command.

Links

Release notes

  • Incremental base backup implementation through the "reuse_backup" global/server option. Possible values are "off" (disabled, default), "copy" (preventing unmodified files from being transferred) and "link" (allowing for deduplication through hard links).
  • Store and show deduplication effects when using "reuse_backup=link".
  • Added transparent support of pg_stat_archiver (PostgreSQL 9.4) in "check", "show-server" and "status" commands.
  • Improved administration by invoking WAL maintenance at the end of a successful backup.
  • Changed the way unused WAL files are trashed, by differentiating between concurrent and exclusive backup cases.
  • Improved performance of WAL statistics calculation.
  • Treat a missing pg_ident.conf as a WARNING rather than an error.
  • Refactored output layer by removing remaining "yield" calls.
  • Check that rsync is in the system path.
  • Include history files in WAL management.
  • Improved robustness through more unit tests.
  • Fixed bug #55: Ignore fsync EINVAL errors on directories.
  • Fixed bug #58: retention policies delete.

PostgreSQL 9.4 Increases Flexibility, Scalability and Performance

Thu, 12/18/2014 - 01:00

18 DECEMBER 2014: The PostgreSQL Global Development Group announces the release of PostgreSQL 9.4, the latest version of the world's leading open source database system. This release adds many new features which enhance PostgreSQL's flexibility, scalability and performance for many different types of database users, including improvements to JSON support, replication and index performance.

Flexibility

With the new JSONB data type for PostgreSQL, users no longer have to choose between relational and non-relational data stores: they can have both at the same time. JSONB supports fast lookups and simple expression search queries using Generalized Inverted Indexes (GIN). Multiple new support functions enable users to extract and manipulate JSON data, with a performance which matches or surpasses the most popular document databases. With JSONB, table data can be easily integrated with document data for a fully integrated database environment.

"JSONB brings PostgreSQL to the JavaScript development community by allowing JSON data to be stored and queried natively. Node.js and other server-side JavaScript frameworks can benefit from the safety and robustness of PostgreSQL, while still storing data in the schema-less format that they prefer," said Matt Soldo, Product Manager, Heroku Postgres.

Scalability

In 9.4, Logical Decoding supplies a new API for reading, filtering and manipulating the PostgreSQL replication stream. This interface is the foundation for new replication tools, such as Bi-Directional Replication, which supports the creation of multi-master PostgreSQL clusters. Other improvements in the replication system, such as replication slots and time-delayed replicas, improve management and utility of replica servers.

"The main reason behind our immediate adoption of PostgreSQL 9.4 in production is the new Logical Decoding feature," said Marco Favale, Cartographic Production Manager of Navionics. "The ability to write custom and flexible output plugins will allow us to transparently collect changes on selected tables and replicate changes where we like, by removing heavier - and more complex to manage - trigger based replication solutions."

"Zalando relies on the stability and performance of hundreds of PostgreSQL database servers to continuously serve millions of customers all around Europe," said Valentine Gogichashvili, Team Lead Database Operations at Zalando Technologies. "We are excited to run time-delayed standby servers which work out of the box, and will evaluate the new bi-directional replication tools as soon as they are released."

Performance

Version 9.4 also introduces multiple performance improvements which will allow users to get even more out of each PostgreSQL server. These include:

  • Improvements to GIN indexes, making them up to 50% smaller and up to 3X faster.
  • Concurrently updatable Materialized Views for faster, more up-to-date reporting.
  • Rapidly reload the database cache on restart using pg_prewarm.
  • Faster parallel writing to the PostgreSQL transaction log.
  • Support for Linux Huge Pages for servers with large memory.

"We will definitely benefit from concurrent refresh of materialised views, delayed standby servers (which will make our disaster recovery even more robust) as well as the usual performance improvements every new release carries on," added Marco Favale.

POWA 1.2 is out !

Tue, 10/28/2014 - 01:00

DALIBO is proud to present a new release of POWA, a performance tool for PostgreSQL.

Realtime traffic analysis and dynamic graphs

POWA is a workload analyzer that gives a clear view of the current activity of your PostgreSQL servers with a query runtime graph and a block hit/read graph along with a chart of time consuming requests over the specified time period.

If you zoom anywhere in one of the graphs, the chart will adjust and show you which queries were running at that time. If you click on a specific query, you will get additional graphs such as read/write time, number of rows affected, local and shared hit, etc.

A bunch of PL functions are also available to access and manage the stats.

New metrics and a better UI

This release includes some new features and some fixes since the first public release.

The core is responsible of statistics gathering. It relies on pg_stat_statements. As a first change, in order to avoid storing useless informations, DEALLOCATE and BEGIN statements are now ignored by the core. The snapshot timestamps were fixed. In order to ease backups and diagnostics, now PoWA history tables are now marked as "to be dumped" by pg_dump. Performance for "per database aggregated stats" were also improved. And last thing, some more metrics were made available throught the SQL API : temporary data, I/O time, average runtime.

The UI was also improved. In addition to displaying the new available metrics, several features were added. First, the UI follows the selected time interval from page to page. The displayed metrics are now human readable. Also, the query metrics are now displayed on each query page. Each page now has a different title, regarding its context. In order to get a better display area, the original database selector as been removed. A menu entry now permits the user to navigate between databases. Several bugs were fixed, like the empty graph bug. Note that the configuration file has changed since the previous release.

For the complete list of changes, please checkout the release notes

For complete installation and upgrading instructions, please checkout the documentation

walbouncer: partial transaction log replication

Wed, 10/22/2014 - 01:00

We are proud to announce walbouncer 0.9 - a tool to filter transaction log. At this point we are moving rapidly closer to a production-ready tool.

The key advantage of walbouncer is that it is no longer necessary to replicate entire database instances. You can filter out entire databases and tablespaces and selectively choose what to replicate.

walbouncer can act as a WAL proxy distributing data flexible to various servers containing different subsets of data.

walbouncer is open source and can be downloaded freely from our website. Currently PostgreSQL 9.4 is supported.

PostgreSQL 9.4 Beta 3 Released

Thu, 10/09/2014 - 01:00

The PostgreSQL Global Development Group has released 9.4 Beta 3, the next beta release of the new version. This beta contains previews of all of the features which will be available in version 9.4, plus corrections for many of the issues discovered by users who tested Beta 2. Please download, test, and report what you find.

The primary change in Beta 3 is a modification of the JSONB data type format in order to make JSONB fields more compressable and reduce storage requirements. This change is not backwards-compatible, so users who loaded data into JSONB fields using 9.4 Beta 1 or Beta 2 will need to pg_dump and restore to upgrade to Beta 3.

Among the other changes made since 9.4 Beta 2 are:

  • Rename pg_recvlogical's --create/--drop to --create-slot/--drop-slot
  • Prevent unbounded delay when starting background worker
  • Remove num_xloginsert_locks GUC, replace with a #define
  • Fix pg_dump's --if-exists for large objects
  • Remove ban on zero length JSON object keys
  • Return NULL from json_object_agg if it gets no rows
  • Log ALTER SYSTEM statements as DDL
  • Fix failure of contrib/auto_explain to print per-node timing information
  • Multiple fixes for TAP checks
  • Support ALTER SYSTEM RESET command
  • Fix power_var_int() for large integer exponents
  • Fix vacuumdb --analyze-in-stages --all order
  • Change the way latency is calculated with pgbench --rate option
  • Support ALTER ... ALL IN with event triggers
  • Remove superuser-only restriction from pg_is_xlog_replay_paused()
  • Fix FOR UPDATE NOWAIT on updated tuple chains
  • Fix Var handling for security barrier views
  • Fix superuser concurrent refresh of matview owned by another
  • Don't track DEALLOCATE in pg_stat_statements
  • Fix corner-case behaviors in JSON/JSONB field extraction operators
  • Change the way pg_basebackup's tablespace mapping is implemented
  • Rework 'MOVE ALL' to 'ALTER .. ALL IN TABLESPACE'
  • Fix core dump in jsonb #> operator
  • Revert psql changes to support wrapped expanded mode
  • Expose -S option in pg_receivexlog
  • Reject duplicate column names in foreign key referenced-columns lists
  • Fix checkpointer crash
  • Many minor fixes to JSON and JSONB functionality
  • Many minor fixes to logical decoding
  • Multiple bug fixes for older issues to be included in an upcoming minor release.
  • More documentation improvements and changes

Beta 3 includes changes to pg_control and to the system catalogs. As such, users who have been testing Beta 1 or Beta 2 will need to upgrade in order to test Beta 3. We suggest using pg_upgrade for this upgrade in order to test that as well.

For a full listing of the features in version 9.4 Beta, please see the release notes. Additional descriptions and notes on the new features are available on the 9.4 Features Wiki Page.

We depend on our community to help test the next version in order to guarantee that it is high-performance and bug-free. Please download PostgreSQL 9.4 Beta 3 and try it with your workloads and applications as soon as you can, and give feedback to the PostgreSQL developers. Features and APIs in Beta 3 will not change substantially before final release, so it is now safe to start building applications against the new features. More information on how to test and report issues

Get the PostgreSQL 9.4 Beta 3, including binaries and installers for Windows, Linux and Mac from our download page.

Full documentation of the new version is available online, and also installs with PostgreSQL.
