MySQL 26.10.0 Early Access Is Here
Oracle MySQL Group
TL;DR - A preview build of the next Innovation release is on MySQL Labs. The headline change is MySQL REST Service as a server component, which serves HTTPS endpoints without a separate MySQL Router. It is not for production.
Newsletter #1: What Happened in September 2026
Maria Nesterova, OurSQL Foundation
TL;DR - The Foundation ran its first booth at Percona Live Amsterdam, launched the OurSQL Universe map of the MySQL ecosystem, and scheduled webinars on row-level recovery (15 Oct) and ProxySQL (3 Nov).
Introducing the MySQL Analytical Replica (Parquet + DuckDB)
dbtrail Blog
TL;DR - An Apache 2.0 tool that follows the binlog, keeps a copy of your MySQL tables as Parquet files in local storage or S3, and lets you query them with DuckDB, so reporting queries stay off production.
Resolving query plan regressions after a MySQL engine upgrade
Chandana DA and Sravan Kumar Gogana, AWS Database Blog
TL;DR - A three-step workflow for RDS and Aurora MySQL upgrades: refresh statistics, compare EXPLAIN ANALYZE plans, then fix each regression with optimizer_switch flags, index hints or composite indexes.
MyVector v1.26.9: Keeping Up With MySQL Innovation
Alkin Tezuysal
TL;DR - The MyVector vector search plugin adds support for MySQL 26.7, the first Innovation release under Oracle's new calendar-based versioning. It also puts the Component architecture from v1.26.5 through heavier testing.
Open FIPS Build, Vectors, and Binlog Server: Marco Tusa at Percona Live
Percona Community
TL;DR - Notes from Marco Tusa's Percona Live Amsterdam keynote. FIPS support moves from the Pro Build to the standard build, vector search lands in Percona Server for MySQL, and an early binlog server is shown.
Amazon RDS for MySQL announces Extended Support minor versions 5.7.44-rds.20260902 and 8.0.46-rds.20260908
AWS What's New
TL;DR - New CVE and bug-fix builds for RDS customers still on MySQL 5.7 and 8.0 under paid Extended Support.
Join MySQL Public Discussion #6 and the November Contributor Summit
Oracle MySQL Group
TL;DR - Public Discussion #6 is on 22 October. The next MySQL Contributor Summit runs online on 4–5 November, continuing Oracle's series of open community sessions.
Access MySQL over MCP with vsql-mcp
VillageSQL
TL;DR - A Rust VillageSQL Server extension that runs a Model Context Protocol (MCP) server inside the database. It offers six tools for schema browsing, read-only queries, query plans and optional writes, with bearer-token auth, table allowlists and row limits.
Hardening EmergencyReparentShard in v25
Vitess
TL;DR - Vitess v25 speeds up emergency failover by filtering relay-log apply by received GTIDs. It also orders candidates consistently by GTID dominance and adds explicit split-brain recovery options.
How Atomic DDL Works in MySQL 8.0
Libing Song
TL;DR - An internals walkthrough of how MySQL 8.0's transactional data dictionary replaced .frm files. It shows how this closed the crash windows that used to leave server metadata out of step with InnoDB's own metadata and data.
PeakAIO contributes support of 8k API nodes to RonDB 26.02.11
Mikael Ronstrom
TL;DR - RonDB, the NDB Cluster fork, goes from 2,039 to 8,191 API nodes in 26.02.11. The change was contributed by PeakAIO, which uses RonDB as the metadata server for its pNFS Lattice file system.
Database News
MySQL BR Conf 2026 Slides: Managed ProxySQL in Your Own AWS Account
ProxySQL
TL;DR - Slides from René Cannaò and Alkin Tezuysal's São Paulo session on ProxySQL.Cloud: bring-your-own-cloud architecture, configuration and day-to-day operations. A recap of the conference is also up.
dbdeployer v2.4.2: Faster MariaDB Sandboxes, Better Cluster Checks, and Five Months of Progress
ProxySQL Blog
TL;DR - v2.4.2 removes a readiness wait that cuts MariaDB sandbox deployment from about eight minutes to 20 seconds and fixes Galera/PXC checks. Recent releases also added MariaDB downloads and PostgreSQL replication checks.
Lakebase Search: State-of-the-art full text and vector search for Postgres
Zhou Sun, Jinjing Zhou, Pranav Aurora et al., Databricks
TL;DR - Two Lakebase Postgres extensions are now GA on AWS and Azure. lakebase_vector does ANN search with RaBitQ-compressed IVF indexes, and lakebase_text replaces GIN with a BM25 index. Both can be fused in one SQL query for hybrid search.
MariaDB Foundation's Test Automation Framework (TAF) 4.0 Release
Jonathan Miller, MariaDB Foundation
TL;DR - The Foundation's performance test framework adds PostgreSQL alongside MariaDB and MySQL. It also generates database and test-case configuration at runtime and changes recovery mode to remove data skew.
For MariaDB, LLMs are the new search engines to win over
Richard Speed, The Register
TL;DR - MariaDB Foundation chairman Kaj Arnö says MariaDB's vector search is ready, but AI coding assistants rarely recommend it. More documentation and real-world use are needed to change that.
TideSQL 5 and MariaDB: the Tides Are Moving Fast
Frédéric Descamps, MariaDB Foundation
TL;DR - The TidesDB-backed storage engine reaches 5.0 with MVCC, secondary indexes, foreign keys, XA, partitioning and online DDL. It now installs from RPM/DEB packages via MariaDB Foundry, with no source build.
Online enabling checksums in PostgreSQL 19
Franck Pachot
TL;DR - PostgreSQL 19's pg_enable_data_checksums() turns on data checksums in the background without downtime. It needs superuser and two background workers, and a crash mid-run means starting over.
Anatomy of a (Postgres) search engine
Eric Ridge, PlanetScale
TL;DR - A walkthrough of inverted indexes: term dictionaries, postings lists and segment merging. It covers how PlanetScale's TIN extension handles MVCC visibility and mixes full-text constraints with ordinary SQL in Postgres. A follow-up, TIN Postgres search is faster, better, and cheaper, reruns a popular Postgres search demo on TIN.
