01.07.2016 - PostgreSQL 9.5: UPSERT, Row Level Security, and Big Data



View PostgreSQL-Press related news.

7 JANUARY 2016: The PostgreSQL Global Development Group announces the release of PostgreSQL 9.5. This release adds UPSERT capability, Row Level Security, and multiple Big Data features, which will broaden the user base for the world's most advanced database. With these new capabilities, PostgreSQL will be the best choice for even more applications for startups, large corporations, and government agencies.

Annie Prévot, CIO of the CNAF, the French Child Benefits Office, said, "The CNAF is providing services for 11 million persons and distributing 73 billion Euros every year, through 26 types of social benefit schemes. This service is essential to the population and it relies on an information system that must be absolutely efficient and reliable. The CNAF's information system is satisfyingly based on the PostgreSQL database management system."

UPSERT

A most-requested feature by application developers for several years, "UPSERT" is shorthand for "INSERT, ON CONFLICT UPDATE", allowing new and updated rows to be treated the same. UPSERT simplifies web and mobile application development by enabling the database to handle conflicts between concurrent data changes. This feature also removes the last significant barrier to migrating legacy MySQL applications to PostgreSQL.

Developed over the last two years by Heroku programmer Peter Geoghegan, PostgreSQL's implementation of UPSERT is significantly more flexible and powerful than those offered by other relational databases. The new ON CONFLICT clause permits ignoring the new data, or updating different columns or relations in ways which will support complex ETL (Extract, Transform, Load) toolchains for bulk data loading. And, like all of PostgreSQL, it is designed to be absolutely concurrency-safe and to integrate with all other PostgreSQL features, including Logical Replication.

Row Level Security

PostgreSQL continues to expand database security capabilities with its new Row Level Security (RLS) feature. RLS implements true per-row and per-column data access control which integrates with external label-based security stacks such as SE Linux. PostgreSQL is already known as "the most secure by default." RLS cements its position as the best choice for applications with strong data security requirements, such as compliance with PCI, the European Data Protection Directive, and healthcare data protection standards.

RLS is the culmination of five years of security features added to PostgreSQL, including extensive work by KaiGai Kohei of NEC, Stephen Frost of Crunchy Data, and Dean Rasheed. Through it, database administrators can set security "policies" which filter which rows particular users are allowed to update or view. Data security implemented this way is resistant to SQL injection exploits and other application-level security holes.

Big Data Features

PostgreSQL 9.5 includes multiple new features for bigger databases, and for integrating with other Big Data systems. These features ensure that PostgreSQL continues to have a strong role in the rapidly growing open source Big Data marketplace. Among them are:

BRIN Indexing: This new type of index supports creating tiny, but effective indexes for very large, "naturally ordered" tables. For example, tables containing logging data with billions of rows could be indexed and searched in 5% of the time required by standard BTree indexes.

Faster Sorts: PostgreSQL now sorts text and NUMERIC data faster, using an algorithm called "abbreviated keys". This makes some queries which need to sort large amounts of data 2X to 12X faster, and can speed up index creation by 20X.

CUBE, ROLLUP and GROUPING SETS: These new standard SQL clauses let users produce reports with multiple levels of summarization in one query instead of requiring several. CUBE will also enable tightly integrating PostgreSQL with more Online Analytic Processing (OLAP) reporting tools such as Tableau.

Foreign Data Wrappers (FDWs): These already allow using PostgreSQL as a query engine for other Big Data systems such as Hadoop and Cassandra. Version 9.5 adds IMPORT FOREIGN SCHEMA and JOIN pushdown making query connections to external databases both easier to set up and more efficient.

TABLESAMPLE: This SQL clause allows grabbing a quick statistical sample of huge tables, without the need for expensive sorting.

"The new BRIN index in PostgreSQL 9.5 is a powerful new feature which enables PostgreSQL to manage and index volumes of data that were impractical or impossible in the past. It allows scalability of data and performance beyond what was considered previously attainable with traditional relational databases and makes PostgreSQL a perfect solution for Big Data analytics," said Boyan Botev, Lead Database Administrator, Premier, Inc.

01.01.2016 - pglogical announced



View PostgreSQL-Press related news.

2ndQuadrant is pleased to announce the availability of pglogical, the next generation in replication systems for PostgreSQL.

pglogical offers Logical Replication as a PostgreSQL extension, which provides the flexibility of trigger-based replication with the efficiency of log-based replication. This ground-breaking new technology has benefits for many key use cases, including:

  • UPGRADE Upgrade PostgreSQL from 9.4 to 9.5, without downtime
  • SCALE OUT Copy all or a selection of database tables to other nodes in a cluster
  • AGGREGATE Accumulate changes from sharded database servers into a Data Warehouse
  • INTEGRATE Feed database changes in real-time to other systems
  • PROTECT Provide backup or high availability for clusters, replacing earlier technologies

Existing PostgreSQL users will find the efficiency of pglogical particularly exciting with preliminary testing demonstrating a significant increase in transaction throughput (without lag) over other replication methods. For example, pglogical performed up to 5 times faster than Slony and Londiste3 on OLTP workloads using pgbench.

For more details and access to binary packages for both the current stable release PostgreSQL 9.4 and the soon to be announced PostgreSQL 9.5 version, visit http://2ndquadrant.com/pglogical/

12.07.2015 - PoWA 3.0.0 released



View PostgreSQL-Press related news.

Paris, December 07 2015

DALIBO is proud to present the third release of PoWA, the PostgreSQL Workload Analyzer.

Realtime traffic analysis and dynamic graphs

PoWA is a workload analyzer that gives a clear view of the activity of your PostgreSQL servers with a query runtime graph and a block hit/read graph along with a chart of time-consuming queries 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.

Better predicate analyzer

The pg_qualstats extension stores new counters. It's now possible to know the most executed predicates in relation to all the related queries. It also tracks non-normalized queries so that it’s possible to execute an EXPLAIN of any query tracked by pg_stat_statements.

Database global optimization

PoWA is now able to use statistics about every predicate used by any query executed on a database to suggest the smallest index set that optimizes every one of those predicates.

In particular, the heuristics place heavy emphasis in consolidating many indexes into one by giving preference to definitions spanning multiple columns. This can provide new information about the actual load and correlation between predicates that are traditionally hard to discover for the DBA.

Index suggestion check

Thanks to the HypoPG extension, the benefits of the suggested index creations can automatically be checked by running the queries against hypothetical indexes. You can see instantly if the suggested index is relevant and how much it'll improve the query.

Credits

DALIBO would like to thank the users and developers who contributed to this release.

PoWA is an open project available under the PostgreSQL License. Any contribution to build a better tool is welcome. You just have to send your ideas, patches or features requests using the GitHub tools or to powa-users@googlegroups.com

10.16.2015 - Ora2Pg 16 released



View PostgreSQL-Press related news.

Paris, France - October 16th, 2015

Ora2Pg 16 released

Version 16.0 of Ora2Pg, a free and reliable tool used to migrate an Oracle database to PostgreSQL, has been officially released and is publicly available for download.

This major release improve PL/SQL code replacement, fixes several bugs and adds some major new features:

  • Full migration of MySQL database, it just work like with Oracle database.
  • Full migration assessment report for MySQL database.
  • New script, ora2pg_scanner, to perform a migration assessment of all Oracle and MySQL instances on a network.
  • Add technical difficulty level in migration assessment.
  • Allow migration assessment on client queries extracted from AUDIT_TRAIL (oracle) or general_log table (mysql).
  • Ora2Pg has a "made in one night" brand new Web site (still need some work) http://ora2pg.darold.net/

Example of technical difficulty level assessment output using the sakila database with some more difficulties:

Total 83.90 cost migration units means approximatively 1 man-day(s). Migration level: B-5

Here are the explanation of the migration level code:

Migration levels: A - Migration that might be run automatically B - Migration with code rewrite and a human-days cost up to 5 days C - Migration with code rewrite and a human-days cost above 5 days Technical levels: 1 = trivial: no stored functions and no triggers 2 = easy: no stored functions but with triggers, no manual rewriting 3 = simple: stored functions and/or triggers, no manual rewriting 4 = manual: no stored functions but with triggers or views with code rewriting 5 = difficult: stored functions and/or triggers with code rewriting

This is to help you to find the database that can be migrated first with small efforts (A and B) and those who need to conduct a full migration project (C).

This release has also some new useful features:

  • Export type SHOW_TABLE now shows additional information about table type (FOREIGN, EXTERNAL or PARTITIONED with the number of partition).
  • Connection's user and password can be passed through environment variables ORA2PG_USER and ORA2PG_PASSWD to avoid setting them at ora2pg command line.
  • Improve PL/SQL replacement on ADD_MONTH(), ADD_YEAR(), TRUNC(), INSTR() and remove the replacement limitation on DECODE().
  • Add detection of migration difficulties in views, was previously reserved to functions, procedures, packages and triggers.
  • Replace values in auto generated configuration file from command line options -s, -n, -u and -p when --init_project is used.
  • Adjust lot of scores following new functionalities in Ora2Pg, ex: autonomous transactions, dblink or synomyms are now more easy to migrate.

There is some new command line options to ora2pg script:

  • -m | --mysql : to be used with --init_project and -i option to inform ora2pg that we work with a MySQL format
  • -T | --temp_dir : option to be able to set a distinct temporary directory to run ora2pg in parallel.
  • --audit_user : option to set the user used in audit filter and enable migration assessment report on queries from AUDIT_TRAIL (oracle) or general_log table (mysql).
  • --dump_as_sheet and --print_header options to be able to compute a CSV file with all migration assessment from a list of oracle database.
  • --dump_as_csv option to report assessments into a csv file. It will not include comments or details, just objects names, numbers and cost.

Some change can break backward compatibility:

  • Change NULL_EQUAL_EMPTY to be disabled by default to force change in the application instead of transforming the PL/SQL.

This release adds some new configuration directives:

  • MYSQL_PIPES_AS_CONCAT: Enable it if double pipe and double ampersand (|| and &&) should not be taken as equivalent to OR and AND.
  • MYSQL_INTERNAL_EXTRACT_FORMAT: Enable it if you want EXTRACT() replacement to use the internal format returned as an integer.
  • AUDIT_USER: Set the comma separated list of user name that must be used to filter from the DBA_AUDIT_TRAIL or general_log tables.
  • REPLACE_ZERO_DATE: the "zero" date: 0000-00-00 00:00:00 is replaced by a NULL by default, use it to use the date of your choice. Useful when you have a NOT NULL constraint.
  • INDEXES_RENAMING: force renaming of all indexes using a name with tablename_columnsnames. Useful for database that have multiple time the same index name or that use the same name than a table.
  • HUMAN_DAYS_LIMIT: default to 5 days, used to set the number of human-days limit for migration of type C.

As usual there is also some bug fixes and Oracle to PostgreSQl conversion adjustments, for a complete list see the changelog.
