PostgreSQL 14 extends its performance gains to the vacuuming In addition to supporting query parallelism, postgres_fdw can now bulk insertĭata on foreign tables and import table partitions with theĭirective. The foreign data wrapper that interfaces with other PostgreSQL databases. Implements this ability in the postgres_fdw, Which are used for working with federated workloads across PostgreSQL and otherĭatabases, can now leverage query parallelism in PostgreSQL 14. PostgreSQL 14 also adds several other performance enhancements to the logicalĭecoding system that powers logical replication. Significant performance benefits for applying large transactions on subscribers. PostgreSQL can now stream in-progress transactions to subscribers, with ![]() Enhancements for Distributed Workloadsĭistributed PostgreSQL databases stand to benefit from PostgreSQL 14. Or a client driver built with version 14 of libpq. Modern PostgreSQL database with the version 14 client As this is a client-side feature, you can use pipeline mode with any To a database, which can significantly improve performance over high latencyĬonnections or for workloads with many small write ( INSERT/ UPDATE/ DELETE) PostgreSQL 14 introduces the ability to pipeline queries On the recent improvements to the management of B-tree indexes by reducing indexīloat on tables with frequently updated indexes. PostgreSQL 14 provides a significant throughput boost on workloads that use manyĬonnections, with some benchmarks showing a 2x speedup. Performance Improvements for Heavy Workloads Multiranges, and other data types can be extended to use multirange support. The range types native to PostgreSQL (dates, times, numbers) support Which lets developers write simpler queries for dealing with complex sequences A multirange is an ordered list of ranges that are nonoverlapping, Released in PostgreSQL 9.2, now have support for noncontiguous ranges throughĭata type. PostgreSQL 14 can be generally extended to other nested data structures, and is This aligns PostgreSQL with syntax that is commonly recognized for PostgreSQL 14 now lets you access JSON data using subscripts, e.g. PostgreSQL has supported manipulating JSONĭata since the release of PostgreSQL 9.2, though retrieval of values used a Source development from a global developer communityĪnd has become the preferred open source relational database for organizations Known for its reliability and robustness, benefits from over 25 years of open PostgreSQL, an innovative data management system Software that is deployed by organizations large and small." "PostgreSQL 14 is a testament to the dedication of the global PostgreSQLĬommunity in addressing feedback and continuing to deliver innovative database ![]() Workloads at scale, enhances observability, and contains new features that helpĪpplication developers," said Magnus Hagander, a PostgreSQL Core Team member. "This latest release of PostgreSQL advances our users' ability to manage data Workloads, query parallelism and logical replication. To PostgreSQL's trend on improving high performance and distributedĭata workloads, with advances in connection concurrency, high-write JSON and support for noncontiguous ranges of data. PostgreSQL continues toĪdd innovations on complex data types, including more convenient access for PostgreSQL 14 brings a variety of features that help developers andĪdministrators deploy their data-backed applications. Version of the world’s most advanced open source database. The PostgreSQL Global Development Group today announced the release of
