Postgres is eating the database world

PostgreSQL isn’t moral a straightforward relational database; it’s an data administration framework with the doubtless to engulf the total database realm. The construction of “Using Postgres for All the pieces” is no longer restricted to a couple elite groups but is turning into a mainstream most consuming observe.

OLAP’s Fresh Challenger

In a 2016 database meetup, I argued that a important gap in the PostgreSQL ecosystem became the lack of a sufficiently proper columnar storage engine for OLAP workloads. Whereas PostgreSQL itself gives hundreds analysis substances, its efficiency in chunky-scale analysis on bigger datasets doesn’t rather measure as much as dedicated exact-time data warehouses.

Take into accout ClickBench, an analytics efficiency benchmark, the establish we’ve documented the efficiency of PostgreSQL, its ecosystem extensions, and derivative databases. The untuned PostgreSQL performs poorly (x1050), but it will reach (x47) with optimization. Furthermore, there are three analysis-linked extensions: columnar retailer Hydra (x42), time-series TimescaleDB (x103), and distributed Citus (x262).

This efficiency can’t be intention about snide, especially in comparison with pure OLTP databases bask in MySQL and MariaDB (x3065, x19700); then all another time, its third-tier efficiency is no longer “proper satisfactory,” lagging in the support of the first-tier OLAP substances bask in Umbra, ClickHouse, Databend, SelectDB (x3~x4) by an disclose of magnitude. It’s a sophisticated field — no longer satisfying satisfactory to make exercise of, but too proper to discard.

Then all another time, the arrival of ParadeDB and DuckDB changed the sport!

ParadeDB’s native PG extension pg_analytics achieves 2d-tier efficiency (x10), narrowing the gap to the top tier to moral 3–4x. Given the further advantages, this stage of efficiency discrepancy is in general acceptable — ACID, freshness and exact-time data with out ETL, no further discovering out curve, no repairs of separate providers and products, now to now not display its ElasticSearch grade chunky-textual negate material search capabilities.

DuckDB specializes in pure OLAP, pushing analysis efficiency to the excessive (x3.2) — other than the academically focused, closed-provide database Umbra, DuckDB is arguably the fastest for useful OLAP efficiency. It’s no longer a PG extension, but PostgreSQL can completely leverage DuckDB’s analysis efficiency boost as an embedded file database by initiatives bask in DuckDB FDW and pg_quack.

The emergence of ParadeDB and DuckDB propels PostgreSQL’s analysis capabilities to the top tier of OLAP, filling the closing crucial gap in its analytic efficiency.

The Pendulum of Database Realm

The distinction between OLTP and OLAP didn’t exist at the inception of databases. The separation of OLAP data warehouses from databases emerged in the Nineties due to the damaged-down OLTP databases struggling to toughen analytics scenarios’ query patterns and efficiency demands.

For a truly prolonged time, most consuming observe in data processing fervent the utilization of MySQL/PostgreSQL for OLTP workloads and syncing data to if truth be told educated OLAP systems bask in Greenplum, ClickHouse, Doris, Snowflake, and a lot others., by ETL processes.

DDIA ch3: Republic of OLTP & Kingdom of Analytics

Love many “if truth be told educated databases,” the strength of dedicated OLAP systems in general lies in efficiency — achieving 1–3 orders of magnitude enchancment over native PostgreSQL or MySQL. The price, then all another time, is redundant data, excessive data disappear, lack of settlement on data values among distributed substances, further labor expense for if truth be told educated skills, further licensing prices, restricted query language energy, programmability and extensibility, restricted tool integration, discouraged data integrity and availability when put next with a total DMBS.

Then all another time, as the announcing goes, “What goes around comes around”. With hardware enhancing over thirty years following Moore’s Regulation, efficiency has elevated exponentially while prices have plummeted. In 2024, a single x86 server can have a total bunch of cores (512 vCPU, EPYC 9754 x2), a lot of TBs of RAM, a single NVMe SSD can retain as much as 64TB / 3M 4K rand IOPS / 14GB /s, and a single all-flash rack can reach a lot of PB; object storage bask in S3 gives on the subject of unlimited storage.

I/O Bandwidth doubles every 3 years

Hardware advancements have solved the data volume and efficiency issue, while database tool trends (PostgreSQL, ParadeDB, DuckDB) have addressed fetch entry to method challenges. This places the elementary assumptions of the analytics sector — the so-known as “gargantuan data” enterprise — below scrutiny.

As DuckDB’s manifesto “Substantial Data is Ineffective” suggests, the era of gargantuan data is over. Most of us don’t have that indispensable data, and most data is seldom queried. The frontier of gargantuan data recedes as hardware and tool evolve, rendering “gargantuan data” pointless for ninety 9% of scenarios.

If ninety 9% of exercise cases can now be handled on a single machine with standalone PostgreSQL / DuckDB (and its replicas), what’s the level of the utilization of dedicated analytics substances? If every smartphone can ship and obtain textual negate material freely, what’s the level of pagers? (With the caveat that North American hospitals aloof exercise pagers, indicating that presumably no longer as much as 1% of scenarios might presumably well additionally undoubtedly need “gargantuan data.”)

The shift in elementary assumptions is steering the database world from a section of diversification support to convergence, from a gargantuan bang to a mass extinction. In this course of, a brand contemporary era of unified, multi-modeled, handsome-converged databases will emerge, reuniting OLTP and OLAP. But who will lead this wide activity of reconsolidating the database discipline?

PostgreSQL: The Database World Eater

There are a plethora of niches in the database realm: time-series, geospatial, file, search, graph, vector databases, message queues, and object databases. PostgreSQL makes its presence felt across all these domains.

A to illustrate is the PostGIS extension, which devices the de facto fashioned in geospatial databases; the TimescaleDB extension awkwardly positions “generic” time-series databases; and the vector extension, PGVector, turns the dedicated vector database niche into a punchline.

This isn’t the first time; we’re witnessing it all another time in the oldest and most consuming subdomain: OLAP analytics. But PostgreSQL’s ambition doesn’t discontinue at OLAP; it’s eyeing the total database world!

PostgreSQL Ecosystem

What makes PostgreSQL so capable? Certain, it’s evolved, but so is Oracle; it’s originate-provide, as is MySQL. PostgreSQL’s edge comes from being every evolved and originate-provide, allowing it to compete with Oracle/MySQL. But its moral specialty lies in its excessive extensibility and thriving extension ecosystem.

Reasons customers prefer PostgreSQL: Open-Provide, Legitimate, Extensible

The Magic of Extreme Extensibility

PostgreSQL isn’t moral a relational database; it’s an data administration framework able to engulfing the total database universe. Besides being originate-provide and evolved, its core competitiveness stems from extensibility, i.e., its infra’s reusability and extension’s composability.

PostgreSQL permits customers to invent extensions, leveraging the database’s general infra to reveal substances at minimal price. As an illustration, the vector database extension pgvector, with moral a lot of thousand lines of code, is negligible in complexity in comparison with PostgreSQL’s millions of lines. Yet, this “insignificant” extension achieves total vector data kinds and indexing capabilities, outperforming hundreds specialised vector databases.

Why? Because pgvector’s creators didn’t must anguish about the database’s general further complexities: ACID, recovery, backup & PITR, excessive availability, fetch entry to control, monitoring, deployment, third-social gathering ecosystem tools, client drivers, and a lot others., which require millions of lines of code to resolve neatly. They most consuming alive to on the wanted complexity of their issue.

To illustrate, ElasticSearch became developed on the Lucene search library, while the Rust ecosystem has an improved subsequent-gen chunky-textual negate material search library, Tantivy, as a Lucene various. ParadeDB most consuming wants to wrap and join it to PostgreSQL’s interface to give search providers and products an identical to ElasticSearch. Extra importantly, it will stand on the shoulders of PostgreSQL, leveraging the total PG ecosystem’s united strength (e.g., hybrid search with pgvector) to “unfairly” compete with another dedicated database.

Pigsty & PGDG has 234 extensions accessible. And there are 1000+ more in the ecosystem

The extensibility brings another giant succor: the composability of extensions, allowing varied extensions to work together, creating a synergistic attain the establish 1+1 » 2. As an illustration, TimescaleDB will likely be blended with PostGIS for spatial-temporal data toughen; the BM25 extension for chunky-textual negate material search will likely be blended with the PGVector extension for semantic fuzzy search, offering blended search capabilities.

Furthermore, the distributive extension Citus can transparently change into a standalone cluster into a horizontally partitioned distributed database cluster. This skill will likely be orthogonally blended with other substances, making PostGIS a distributed geospatial database, PGVector a distributed vector database, ParadeDB a distributed chunky-textual negate material search database, and so forth.

What’s more indispensable is that extensions evolve independently, with out the cumbersome need for major department merges and coordination. This permits for scaling — PG’s extensibility lets a gargantuan various of groups explore database chances in parallel, with all extensions being optional, no longer affecting the core functionality’s reliability. Those substances which are weak and sturdy have the likelihood to be stably integrated into the major department.

PostgreSQL achieves every foundational reliability and agile functionality by the magic of excessive extensibility, making it an outlier in the database world and changing the sport principles of the database landscape.

Recreation Changer in the DB Enviornment

The emergence of PostgreSQL has shifted the paradigms in the database domain: Teams endeavoring to craft a “contemporary database kernel” now face a heroic trial — stand out against the originate-provide, feature-rich Postgres. What’s their uncommon worth proposition?

Till a modern hardware step forward occurs, the advent of useful, contemporary, general-reason database kernels appears to be like unlikely. No singular database can match the general prowess of PG, bolstered by all its extensions — no longer even Oracle, given PG’s ace of being originate-provide and free 😉

A pickle database product might presumably well additionally prick out a field for itself if it will outperform PostgreSQL by an disclose of magnitude in specific points (in general efficiency). Then all another time, it generally doesn’t hold prolonged forward of the PostgreSQL ecosystem spawns originate-provide extension picks. Opting to invent a PG extension rather than a total contemporary database gives groups a crushing bustle succor in enjoying bag-up!

Following this logic, the PostgreSQL ecosystem is poised to snowball, accruing advantages and inevitably involving in the direction of a monopoly, mirroring the Linux kernel’s field in server OS inner about a years. Developer surveys and database construction reviews advise this trajectory.

StackOverflow’s Database Trends Over the Previous 7 Years

PostgreSQL has prolonged been the well-liked database in HackerNews & StackOverflow. Many contemporary originate-provide initiatives default to PostgreSQL as their major, if no longer most consuming, database various. And a lot contemporary-gen companies are going All in PostgreSQL.

As “Radical Simplicity: Lawful Utilize Postgres” says, Simplifying tech stacks, decreasing substances, accelerating construction, lowering risks, and adding more substances will likely be carried out by “Lawful Utilize Postgres.” Postgres can substitute many backend applied sciences, including MySQL, Kafka, RabbitMQ, ElasticSearch, Mongo, and Redis, with out distress serving millions of customers. Lawful Utilize Postgres is no longer restricted to a couple elite groups but turning into a mainstream most consuming observe.

What Else Can Be Done?

The endgame for the database domain appears to be like predictable. But what attain we attain, and what must we attain?

PostgreSQL is already a shut to-splendid database kernel for the overwhelming majority of scenarios, making the intention of a kernel “bottleneck” absurd. Forks of PostgreSQL and MySQL that tout kernel changes as promoting points are essentially going nowhere.

This is an identical to the issue with the Linux OS kernel this day; despite the plethora of Linux distros, all people opts for the same kernel. Forking the Linux kernel is considered as creating pointless difficulties, and the enterprise frowns upon it.

Accordingly, the major struggle is no longer the database kernel itself but two instructions— database extensions and providers and products! The outmoded pertains to inner extensibility, while the latter relates to exterior composability. Mighty bask in the OS ecosystem, the competitive landscape will listen on database distributions. In the database domain, most consuming these distributions centered around extensions and providers and products stand a likelihood for closing success.

Kernel remains lukewarm, with MariaDB, the fork of MySQL’s mother or father, nearing delisting, while AWS, making the most of offering providers and products and extensions on top of the free kernel, flourishes. Funding has flowed into a gargantuan various of PG ecosystem extensions and restore distributions: Citus, TimescaleDB, Hydra, PostgresML, ParadeDB, FerretDB, StackGres, Aiven, Neon, Supabase, Tembo, PostgresAI, and our fetch PG distro — — Pigsty.

A predicament inner the PostgreSQL ecosystem is the impartial evolution of many extensions and tools, missing a unifier to synergize them. As an illustration, Hydra releases its fetch equipment and Docker describe, and so does PostgresML, every distributing PostgreSQL photography with their fetch extensions and most consuming their fetch. These photography and applications are a ways from comprehensive database providers and products bask in AWS RDS.

Even provider providers and ecosystem integrators bask in AWS fall short in front of a gargantuan various of extensions, unable to encompass many due to the varied causes (AGPLv3 license, security challenges with multi-tenancy), thus failing to leverage the synergistic amplification doubtless of PostgreSQL ecosystem extensions.

Many crucial extensions are no longer accessible on Cloud RDS (PG 16, 2024–02–29), Confirm the chunky extension list for minute print: Pigsty RDS & PGDG / AWS RDS PG / Aliyun RDS PG

Extensions are the soul of PostgreSQL. A Postgres with out the freedom to make exercise of extensions is bask in cooking with out salt, a giant constrained.

Addressing this issue is one in every of our major targets.

Our Decision: Pigsty

No topic earlier exposure to MySQL and MSSQL, when I first extinct PostgreSQL in 2015, I became convinced of its future dominance in the database realm. Almost a decade later, I’ve transitioned from an particular individual and administrator to a contributor and developer, witnessing PG’s march toward that procedure.

Interactions with diverse customers revealed that the shortcoming in the database discipline isn’t the kernel anymore— PostgreSQL is already satisfactory. The exact issue is leveraging the kernel’s capabilities, which is the reason in the support of RDS’s booming success.

Then all another time, I beget this skill wants to be as accessible as free tool, bask in the PostgreSQL kernel itself — accessible to every body, no longer moral renting from cyber feudal lords.

Thus, I created Pigsty, a battery-included, originate-provide PostgreSQL distribution as an originate-provide RDS Alternative, which objectives to harness the collective energy of PostgreSQL ecosystem extensions and democratize fetch entry to to excessive-quality database providers and products.

Pigsty stands for PostgreSQL in Great STYle

We’ve defined six core propositions addressing the central issues in PostgreSQL database providers and products: Extensible Postgres, Legitimate Infras, Observable Graphics, Readily accessible Providers and products, Maintainable Toolbox, and Composable Modules.

The initials of these worth propositions provide another acronym for Pigsty:

Postgres, Infras, Graphics, Service, Toolbox, Yours.

Your graphical Postgres infrastructure provider toolbox.

Extensible PostgreSQL is the linchpin of this distribution. In the currently launched Pigsty v2.6, we integrated DuckdbFDW and ParadeDB extensions, hugely boosting PostgreSQL’s analytical capabilities and guaranteeing every body can with out distress harness this energy.

Our procedure is to integrate the strengths inner the PostgreSQL ecosystem, creating a synergistic force comparable to the Ubuntu of the database world. I beget the kernel debate is settled, and the exact competitive frontier lies here.

Developers, your picks will shape the future of the database world. I am hoping my work helps you better accomplish the most of the world’s most evolved originate-provide database kernel: PostgreSQL.
