Ideas, releases, practical guides, and perspectives from the people building with MySQL.
The MySQL team would like to thank everyone in the community who contributed bug reports, patches, pull requests, and continued feedback that became part of the MySQL 26.7 release. As always, community contributions help make MySQL better for everyone. In this release, we received contributions across the MySQL Server Optimizer, Parser, Prepared Statements, Performance Schema, […]
Users can now provision a DB system with an IPv6 address when the selected subnet supports IPv6. Applications can then reach the DB system through its IPv6 primary endpoint. IPv6 connectivity, familiar MySQL Modern cloud applications increasingly use IPv6 to expand address capacity, simplify large network estates, and support long-term infrastructure modernization. Yet a single […]
1. Purpose and scope
This performance investigation aims to look into the read/write performance of Percona Server for MySQL 8.4 and how it changed between versions released in 2026:
- 8.4.8-8 released on 12 March 2026
- 8.4.10-10 released on 30 June 2026
- 8.4.11-11 released on 20 August 2026
We want to see if there are improvements in scalability and performance in OLTP read/write operations, where the improvements are most noticeable and how they were achieved. For some readers this material might help with making the decision whether upgrading to a newer version is worth the effort.
An important note is that the new features or security patches will not be taken into consideration.
Measuring Latency (Percentiles) and Resource Utilization (CPU, RAM, I/O) is not in the scope of this post.
2. Configuration and Methodology

Oracle plans to move MySQL security updates toward a monthly cadence, supplementing the current quarterly Critical Patch Update (CPU) schedule. These monthly Critical Security Patch Update (CSPU) releases will be issued only when needed to address critical security or stability issues; they are not a fixed monthly release commitment. These CSPU releases will focus on […]
VillageSQL Server 0.0.6 is now available. This release advances the mainline to MySQL Server 8.4.11 and adds support for MySQL Server 9.7.2 and Percona Server 8.4.10.
Highlights of this release include the following:
- An extension can now log you in, so your identity provider decides who gets into the database.
- Extensions can call the server's own internal component services, which opens up a large part of the MySQL surface area.
- A privilege of its own now covers extension management, so you can grant that and nothing else.
- If you build a custom type incorrectly, you find out when you compile the extension or when you install it, rather than when someone runs a query.
VillageSQL now runs on MySQL Server 9.7 and Percona Server 8.4
VillageSQL Server 0.0.6 adds a mysql-9.7 build that
tracks the MySQL Server 9.7.2 tree, and a
percona-8.4 build …
Two recent posts on the Percona blog caught my attention. In Replicating from InnoDB into a DuckDB storage engine and The DuckDB MySQL engine at 500 GB, Evgeniy Patlan wired DuckDB into mysqld as a storage engine, pointed row-based replication at it, and measured it at TPC-H scale factor 500. The numbers are striking: loads 25 times faster than InnoDB, one fifth of the disk, and the full 22-query TPC-H suite done in 186 seconds where InnoDB needed about 28 hours and never finished four of the queries.
The posts are also honest about the cost. The work is experimental. The worst bug found was silent data loss on every replicated transaction: the two-phase commit code for mixed-engine transactions dropped prepared DuckDB transactions …
The MySQL Community team will continue to be active across conferences, user group meetups, open source events, and regional community activities throughout August, September, and October 2026. While some of our August events were featured in our previous event update, we’ve included them here again with the latest information. Whether you’re interested in learning about MySQL 9.7 LTS, exploring the latest features in […]
MySQL Galera Cluster reaches end of life on September 30, 2026. This guide compares five practical paths forward - MariaDB Galera Cluster, Percona XtraDB Cluster, self-managed MySQL, managed cloud MySQL and Tungsten Cluster - with the trade-offs, migration effort and long-term risks of each.
Tối ưu chỉ mục (index) trong MySQL là kiến thức cơ bản mà nhiều dev PHP mới hay bỏ qua. Có bạn dev mới ra trường nhắn tin kể cho chúng tôi về một buổi tối khá căng thẳng. Ứng dụng quản lý đơn hàng bạn viết chạy mượt suốt mấy tuần thử nghiệm với vài trăm bản ghi. Nhưng khi khách hàng thật bắt đầu dùng, dữ liệu tăng lên vài chục nghìn dòng. Trang danh sách đơn hàng bỗng dưng tải chậm tới mức khách phàn nàn. Bạn kiểm tra code PHP mãi không thấy lỗi gì. Tới khi một anh senior xem qua mới phát hiện câu truy vấn tìm đơn hàng theo mã khách chưa hề có chỉ mục. Điều này khiến MySQL phải quét qua toàn bộ bảng mỗi lần tìm kiếm. Đây là tình huống khá phổ biến ở nhiều dev PHP mới vào nghề. Chỉ mục trong MySQL là kiến thức nền tảng, nhưng lại thường bị …
MySQL Galera Cluster maintenance ends September 30, 2026, while MySQL 8.0 has already reached end of life. Learn what these overlapping lifecycle changes mean, what risks increase after support ends, and what teams should decide before the Galera EOL deadline.
