Dissecting the MySQL 8.0 Performance Regression on oltp_update_non_index

2026-04-16T00:00:00+00:00

The performance regression in MySQL 8.0 is well known, but it is still not fully understood. That is because it is not a regression caused by one obvious bottleneck. MySQL 8.0 introduced many new designs and refactored major subsystems, so the gap comes from a combination of configuration defaults, architectural trade-offs, and many small overheads spread across different layers.

Since my previous post on Village SQL, life has been filled with too many other things. But finally I was able this past weekend to circle back and try to write my own extension.

The Village SQL TL;DR -> MySQL with PostgreSQL like extensions.

The documentation on writing new extensions seems complete, but I have run into issues that are probably caused by me, and

Reducing P999 Latency in Distributed Databases with TiDB 8.5

2026-04-07T13:00:46+00:00

Reducing P999 latency in distributed databases is one of the hardest challenges in modern OLTP systems. A handful of slow requests can cascade across services, break SLOs, and directly impact business outcomes, especially in latency-sensitive environments like trading platforms and real-time applications. This is the challenge of tail latency. As systems scale, variability compounds: queueing [&

What enterprise devops teams should learn from SaaS

Starting from PostgreSQL’s fsync Failure

2026-04-06T21:00:37+00:00

♦Introduction

In 2018, the PostgreSQL community discovered a severe problem that had existed for 20 years: when fsync() fails, PostgreSQL's handling could lead to silent data loss. This incident, known as "fsyncgate", not only revealed an architectural flaw in PostgreSQL itself, but also exposed a deep conflict between the Linux kernel, file systems, and databases regarding I/O erro

Sysbench vs MariaDB on a small server: using the same charset for all versions

2026-04-06T03:38:13+00:00

This has results for sysbench vs MariaDB on a small server. I repeated tests using the same charset (latin1) for all versions as explained here. In previous results I used a multi-byte charset for modern MariaDB (probably 11.4+) by mistake and that adds a 5% CPU overhead for many tests.

tl;dr

MariaDB has done much better than MySQL at avoid regressions from code bloat.

Sysbench vs MySQL on a small server: no new regressions, many old ones

2026-04-06T02:43:34+00:00

This has performance results for InnoDB from MySQL 5.6.51, 5.7.44, 8.0.X, 8.4.8 and 9.7.0 on a small server with sysbench microbenchmarks. The workload here is cached by InnoDB and my focus is on regressions from new CPU overheads.
In many cases, MySQL 5.6.51 gets about 1.5X more QPS than modern MySQL (8.0.x thru 9.7). The root cause is new CPU overhead, possibly from code bloat.

We spoke to Peter Zaitsev, founder of database support specialist Percona, to discuss what MySQL users should be doing now and whether there’s still life in the old database yet.

Lessons from Using Claude Code to Implement Double Write Buffer in PostgreSQL

2026-03-24T22:30:24+00:00

I’ve been exploring how to use Claude Code to help write database kernel code. The specific task was implementing a Double Write Buffer in PostgreSQL, modeled after InnoDB’s implementation. Claude was fast at writing the code, but I ran into a problem along the way: it can’t do design.
The Buffer I/O vs Direct I/O Gap
I asked Claude to implement a DWB in PostgreSQL following InnoDB’s

MariaDB Doesn't Depend on MySQL

2026-03-24T16:00:00+00:00

When MariaDB was first announced in 2009 by Michael “Monty” Widenius, it was positioned as a “fork of MySQL”. I think that was a Bad Idea™. Okay, maybe it wasn’t a bad idea as such. After all, MariaDB indeed is a fork of MySQL. But what is a fork in the software sense, and how is this reflected in MariaDB?

A fork is a software project that takes the source code of another project an

Building and testing MySQL 9.7.0 early access build on macOS

2026-03-24T14:25:18+00:00

Oracle released 9.7.0 community early access build, which is a part of their work towards fulfilling their new promises to the community. This is great news for community testing and I did my part in my usual way (previously: 8.0.45 / 8.4.8 / 9.6.0).

No changes from 9.6.0: the current Xcode (26.3) builds the 9.7.0 early access build fine, LLVM 21 still fails (bug #119246).
