This capability is implemented in postgres fdw, the foreign data wrapper that interfaces with other PostgreSQL databases, in this release. In PostgreSQL 14, foreign data wrappers, which are used to interact with federated workloads across PostgreSQL and other databases, can now make use of query parallelism. In addition, PostgreSQL 14 improves the performance of the logical decoding system, which is used to power logical replication. PostgreSQL may now stream in-progress transactions to subscribers when utilising logical replication, resulting in significant performance gains when applying big transactions to subscribers. Improved Support for Distributed Workloads

Due to the fact that pipeline mode is a client-side feature, you can use it with any current PostgreSQL database using either the version 14 client or a client driver created using version 14 of libpq. PostgreSQL 14 offers the ability to pipeline queries to a database, which can greatly increase performance across high-latency connections or for workloads with a high number of tiny write operations (INSERT/UPDATE/DELETE). This version builds on previous enhancements to B-tree index management by decreasing index bloat on tables with frequently updated indexes.Įxciting Times Ahead for India’s Lab-Grown Organ Market PostgreSQL 14 significantly improves throughput for tasks that need a large number of connections, with some evaluations indicating a 2x speedup.

libpq now supports pipelined queries, which can significantly increase throughput over high-latency connections.

Extended statistics on expressions can now be collected, allowing for more precise planning of outcomes for complex searches.

When the database approaches a transaction ID wraparound condition, VACUUM automatically becomes more aggressive and skips non-essential cleanup.

Updates to B-tree indexes are more efficiently managed, resulting in less index bloat.

Parallel queries, heavily concurrent workloads, partitioned databases, logical replication, and vacuuming have all seen significant performance increases.

Multiranges have been added to range types, enabling the representation of non-contiguous data ranges.

Subscripting operators have been added to the jsonb and hstore types in this release.

Subscripting can now be used with any data type for which the notation is useful, not only arrays.

For common table expressions, the SQL-standard SEARCH and CYCLE options have been implemented.

OUT parameters can now be used to return data from stored procedures.

PostgreSQL 14 introduces a number of new features and enhancements, including the following:

PostgreSQL 14 demonstrates the global PostgreSQL community’s commitment to resolving criticism and continuing to develop innovative database software that is utilised by both large and small enterprises.” Magnus Hagander, a PostgreSQL core team member, stated that “PostgreSQL’s most recent release improves our users’ capacity to handle data workloads at scale, improves observability, and includes new capabilities that benefit application developers. With advancements in connection concurrency, high-write workloads, query parallelism, and logical replication, this latest version continues PostgreSQL’s history of boosting high performance and distributed data workloads. PostgreSQL continues to make advancements in the area of complex data types, including more accessible JSON access and support for non-contiguous data ranges. It introduces several new features that make it easier for developers and administrators to implement data-driven applications. PostgreSQL 14 is the next major release of PostgreSQL, the most powerful open source database globally.
