With Deferred Maintenance and Maintenance Events, customers can better align database maintenance with their business schedules and operational processes to reduce disruption. Customers can now temporarily disable disruptive maintenance which requires system reboots. To ensure the ongoing security of customer environments, zero-downtime security patches will continue to be applied regularly. Additionally, […] Aug 14 2026 Curated MySQL Data Sets for Realistic Testing Posted by Ronald Bradford on Fri 14 Aug 2026 00:00 UTC Synthetic benchmarks have their place, but I have always preferred working with real data. Not client production data — that stays private — but publicly available datasets that reflect the messy shapes, skewed distributions, and indexing challenges you encounter in the wild.

Now, there’s even more to explore. We’ve added new ways to discover the projects and products that make up the broader MySQL ecosystem, find upcoming MySQL events, and search the wealth of content shared by the community. At the center of these […] Aug 13 2026 Replicating from InnoDB into a DuckDB storage engine Posted by MySQL Performance Blog on Thu 13 Aug 2026 17:23 UTC Tags: Open Source, innodb, storage engine, Insight for DBAs, Percona Software, MySQL Our first post showed MySQL 9.7 with one change: mark a table ENGINE=DuckDB and its analytical queries run in DuckDB instead of InnoDB. The question we kept getting after that was about replication. Can you keep a normal InnoDB primary for the writes, and run a replica where the big tables are ENGINE=DuckDB? Then the heavy reports run on a column store, and ordinary MySQL replication keeps it current. No export job. No second database to sync by hand. So we tried it. The first run failed, and it failed in a way that is easy to miss: the replica took every transaction, reported success, and stored nothing. We tracked down why, fixed it, and the whole test suite passes now. This post is what we tested, how we checked it, the bug we found, and where it stands. It’s still an experiment, not production software. The code and the test harness are on GitHub under GPLv2: … [Read more] Aug 12 2026 COSCUP 2026: Planning your upgrade to MySQL 9.7 Posted by Ronald Bradford on Wed 12 Aug 2026 00:00 UTC I recently had the pleasure of presenting Planning your upgrade to MySQL 9.7 at COSCUP 2026 in Taipei, Taiwan.

Aug 08 2026 MySQL and MariaDB High Availability vs. Disaster Recovery: What’s the Difference (and Why It Matters) Posted by Continuent on Sat 08 Aug 2026 09:51 UTC High availability keeps MySQL and MariaDB applications running through routine local failures, while disaster recovery restores service after a site or regional outage. This article explains how RTO, RPO, distance, synchronous replication and asynchronous replication shape each strategy, and how Continuent Tungsten Cluster combines local HA with multi-site DR. Aug 07 2026 The DuckDB MySQL engine at 500 GB Posted by MySQL Performance Blog on Fri 07 Aug 2026 12:09 UTC Tags: Open Source, innodb, storage engine, Benchmarks, Percona, MySQL We ran DuckDB MySQL storage engine at scale factor 500. It is around 500 GB of raw TPC-H, three billion lineitem rows on an 80-core server with 187 GB of RAM. Three engines on the same box: InnoDB, our MySQL+DuckDB engine, and plain DuckDB as the reference. Here is what came out. InnoDB finished 18 of the 22 queries and spent more than 28 hours of query time on them. Four never finished. Our engine ran all 22 in about three minutes. It loaded the data 25 times faster than InnoDB, and it used 5 times less disk. On the queries it stays close to plain DuckDB, and on a few it is ahead. It’s still an experiment, not production software. Code and the benchmark harness are on GitHub under GPLv2: https://github.com/Percona-Lab/ducksdb-mysql-engine. The machine, and how we ran it One server, 80 cores, 187.5 GB RAM. …[Read more] Aug 04 2026 MySQL 8.0.17 GTID Crash Safety Improvement Posted by Jean-François Gagné on Tue 04 Aug 2026 22:22 UTC Tags: Replication, innodb, bugs, consistency, gtid, data loss, MySQL 8.0, dbdeployer, Documentation Bugs, MySQL 8.0.17 I have known for some times that there is an interesting improvement in MySQL 8.0.17 regarding GTID Crash Safety, but I have not had the time nor the need to look into it before.  When writing my last post (Understanding MySQL Replication "fatal error 1236": [...]), I saw something interesting related to this, and it is now time to cover this on my blog.
