Percona Operator for MySQL 1.3.0 adds autopilot tuning, zero-data-loss async failover and encrypted PITR. A new tool called innodump extracts data from InnoDB, MyISAM and MyRocks files without a running server. MariaDB 11.8 fixes an InnoDB mutex regression dating back to 10.5, taking one benchmark from 20K to 57K QPS. Percona's vector search benchmark shows pgvector scaling 21.7 times under 32 clients while InnoDB-based engines stayed near 1x. FOSDEM 2027 gets a new M-Ecosystem devroom and MySQL Belgian Days opens its call for papers for January 28-29, 2027 in Brussels. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How can I change a MySQL account password without causing downtime for connected clients? In MySQL 8.0 and later, use ALTER USER with RETAIN CURRENT PASSWORD to let an account accept both the old and new password simultaneously while clients roll over, then run DISCARD OLD PASSWORD once all clients have switched. This avoids both an outage and the need to create a duplicate account. _Rolling out password rotations without breaking connections is easier to plan with MySQL guidance like this on daily.dev._ ### How much faster is MariaDB 11.8 compared to 10.4 on in-memory workloads? MariaDB 11.8 fixes a regression in InnoDB's LRU promotion logic that had held the buf_pool.mutex too eagerly since version 10.5. The fix takes one of Mark Callaghan's benchmark tests from 20,000 to 57,000 queries per second, and 11.8 now beats 10.4 by 7 to 9 percent on that workload. _Teams planning a MariaDB upgrade can track performance regressions and fixes like this on daily.dev._ ### How did pgvector perform against InnoDB-based MySQL engines in a vector search benchmark? In a benchmark using 990,000 OpenAI embeddings across MariaDB 11.8/12.3, AliSQL, pgvector, Valkey and Percona Search for MongoDB, pgvector scaled 21.7 times under 32 concurrent clients while the InnoDB-based engines stayed near 1x scaling. Index build times across the engines ranged from 1.9 minutes to 6.7 hours. _Comparing vector search engines before committing to one gets easier by following benchmarks like this on daily.dev._ ## Similar posts on daily.dev - [Village News: MySQL News \+ Events \(21 September 2026\)](https://daily.dev/posts/village-news-mysql-news-events-21-september-2026--wnkidmm4l) · Planet MySQL · 0 upvotes · 0 comments - [MariaDB Foundation Newsletter – September 2026](https://daily.dev/posts/mariadb-foundation-newsletter-september-2026-bbuwtzgde) · MariaDB.org · 0 upvotes · 0 comments - [MySQL Community Meetups Fall 2026](https://daily.dev/posts/mysql-community-meetups-fall-2026-lhhlw5kax) · Planet MySQL · 0 upvotes · 0 comments - [The clock's ticking for MySQL 8.0 as end of life looms](https://daily.dev/posts/the-clock-s-ticking-for-mysql-8-0-as-end-of-life-looms-jasht3a4g) · The Register · 0 upvotes · 0 comments --- Tags: [#infrastructure](https://daily.dev/tags/infrastructure), [#database](https://daily.dev/tags/database), [#postgresql](https://daily.dev/tags/postgresql), [#mysql](https://daily.dev/tags/mysql), [#vector-search](https://daily.dev/tags/vector-search) [View this post on daily.dev](https://daily.dev/posts/village-news-mysql-news-events-29-october-2026--oxos36qpr) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Village News: MySQL News + Events (29 October 2026)","url":"https://daily.dev/posts/village-news-mysql-news-events-29-october-2026--oxos36qpr","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/village-news-mysql-news-events-29-october-2026--oxos36qpr"},"datePublished":"2026-10-30T12:21:25.065Z","dateModified":"2026-10-30T12:21:54.396Z","description":"This roundup gathers MySQL and database news and upcoming events for the week of October 29, 2026.
