GripNews🌘 Jepsen 分析報告：MariaDB Galera Cluster 12.1.2 的數據一致性缺陷
➤ 當高可用性遇上現實：Galera Cluster 的承諾與數據遺失真相
✤ https://jepsen.io/analyses/mariadb-galera-cluster-12.1.2
著名的分散式系統測試機構 Jepsen 對 MariaDB Galera Cluster 12.1.2 進行了深入分析。報告指出，該系統儘管宣稱具備極高的一致性與「無交易遺失」的承諾，但在實際測試中卻頻繁出現交易遺失現象，特別是在節點崩潰或網路分區的情境下。此外，研究發現 Galera Cluster 無法達到其宣稱的隔離級別（介於序列化與可重複讀之間），不僅存在「遺失更新」（Lost Update）問題，還會出現「髒讀」或「過時讀取」（Stale Read）。這項研究揭示了該資料庫在嚴苛環境下的穩定性與正確性仍有明顯缺口。
+ 這份報告太重要了。企業級應用通常依賴 Galera 的同步複製，結果發現連最基本的 ACID 保

JepsenA new #Jepsen report, on MariaDB Galera Cluster 12.1.2. Two cases of write loss, along with P4 (Lost Update) and Stale Read in healthy clusters.
I arrived a “ACID compliant transfer of bindings” and I’m wondering if @aphyr of #jepsen fame has been consulted. #regicideReport @cstross

A new #Jepsen report: we demonstrate data loss and persistent split-brain in the NATS streaming system, in response to simulated power failures/OS crashes.
A new #Jepsen release, 0.3.10, brings improved support for controllable random value generation, and running tests inside Antithesis. Jepsen's composable generator system has also been extracted to a minimal library, making it easier to re-use in other systems.
Su-Sheeallow me to have a little nerd crush because I'm watching a talk about #jepsen and for me it's pretty much the coolest thing ever about testing AND databases 😍
