Found yourself on a data project and have no idea what they all are talking about? Feel excluded from all the fun discussions in the office kitchen? If only there were a humongous guide going over all the concepts and buzzwords...
Turso is becoming the LLVM of databases: one modern, reliable Rust core with many SQL frontends. After rewriting SQLite, we are now building Postgres.
Homescale, PlanetScale at home.
How to make 768 distinct Postgres servers look like 1 to your applications.
Every so often the Earth produces a signal that is impossible to ignore. This graph is one of them. It shows sea-surface temperatures in the Niño 3.4 region of the equatorial Pacific, one of the most important parts of the Earth's climate system. Each blue line represents a different year since 1982. The red line is…
I prefer strict tables in SQLite because they avoid some datatype problems, such as putting text in number columns.
PgBouncer is single-threaded, so a single process caps out at one CPU core no matter the box size. See how ClickHouse Managed Postgres runs a peered fleet of PgBouncer processes with so_reuseport to scale pooling across every core — with benchmarks showin
A real quarter of UK SME books, 59 transactions, 68 minutes, $2.73 of tokens — and a VAT return within 7 pence of the human-prepared one.
Pruning agent context down to what the answer actually needs, while keeping 96% of recall
In this blog post, we will explain how strict memory overcommit protects your database from catastrophic OOM (out of memory) kills. We will also share how a one character kernel bug forced us to temporarily disable this setting. Finally, we will explain our heuristic for determining the right memory overcommit limit…
Keeping workflow state and application data in the same Postgres database lets one transaction update both, simplifying idempotency and atomicity.
Almost every traditional database keeps its write-ahead log and data files on one machine's disk, which is the root cause of data loss risk, expensive read replicas and high-availability clones, and analytics queries that drag down transactions.
Discover the top PostgreSQL 19 features, including built-in REPACK CONCURRENTLY, SQL property graph queries (SQL/PGQ), and logical replication updates.
This article was written by Marco Manino and Alberto Carretero, dqlite team at Canonical. 1. Anatomy of a SQLite bug Recently SQLite published a new version with a fix to a long-standing bug in the way that the Write Ahead Log (WAL) is checkpointed that leads to the corruption of the database. The important aspect […]
Late interaction makes retrieval more precise but turns every document into many vectors. Asymmetric quantization keeps query vectors precise and stores…
How we built WAL-RUS, an open-source Rust-based Postgres backup tool that reduces virtual memory usage by over 70% compared to WAL-G while maintaining full compatibility.
After the success of using agents to improve query performance through autoresearch , I wanted to try something more ambitious. I rewrote PostHog's…
This year, British Column has moved to year-round Pacific Time. How does that affect date data?
I ran a pairwise-choice experiment on my Greyhound to rank his favorite treats, measure side bias, and accidentally turn bedtime snacks into a statistics problem.
A tour of the-stats-duck v0.6.0: a one-shot data profiler, regression and bootstrap CIs in plain SQL, ten new distributions, and SAS/XPT imports that got 52x faster — with live Bedevere demos you can poke at.
Discover how Postgres managed by ClickHouse compares to its peers in a reproducible, open benchmark.

Walk through DuckDB's internals: how it skips serialization overhead, parses and optimizes SQL, and stores data in columnar row groups with zone maps.
ClickHouse was released in open source on Jun 15 2016, ten years ago. Since then, it became the most popular open source analytical database with more than 2000 contributors.
TimescaleDB compression with hypercore - columnar storage with up to 98% ratio in PostgreSQL. segmentby/orderby configuration and a benchmark for IoT and time-series.
Sadly, taking away valuable disclosure avoidance tools doesn't make fundamental trade-offs go away.
