michabbb#Directus layers a blazingly fast #NodeJS API on top of any existing SQL database. No schema changes needed, works with what you already have.
🗄️ Database Freedom:
#PostgreSQL, #MySQL, #SQLite, #MariaDB, MS-SQL, #CockroachDB & #OracleDB — you choose, Directus connects.
🎨 No-Code Admin Dashboard
Built with #VueJS, intuitive and secure. Non-technical users can manage content without any training required.
🔌 Fully Extensible & White-Label Ready
Ignite Realtime NewsWe are exploring support for #MariaDB, #Firebird and #CockroachDB in Openfire. This includes early pull requests and discussion of trade-offs, maintenance cost and real-world demand.
We would love community input before proceeding further.
Is this valuable, or more trouble than it is worth?
Experimenting with MariaDB, Firebird and CockroachDB Support in Openfire
I have recently started experimenting with adding support for three additional databases in Openfire: MariaDB, Firebird and CockroachDB. This work is still exploratory. Before committing to this direction, I would like to get a better understanding of whether this is actually valuable to the Openfire community. I have prepared initial pull requests for each database: MariaDB: https://github.com/igniterealtime/Openfire/pull/3240 (OF-3239 in our issue tracker) Firebird: https://github.com/igni...

GripNews🌘 不可穿越：利用列級別安全性的精細訪問控制
➤ 提升資料安全，簡化多租戶架構與區域限制
✤ https://www.cockroachlabs.com/blog/fine-grained-access-control-row-level-security/
本文介紹了 CockroachDB 25.2 版本推出的列級別安全性 (Row-Level Security, RLS) 功能。RLS 允許開發者和運營者在資料庫層面直接定義和強制執行基於使用者角色或屬性的數據訪問策略，從而提高數據安全性和合規性，並簡化應用程式的複雜性。文章深入探討了 RLS 在多租戶和多區域部署情境下的應用，以及它如何透過共享表格和精細策略有效管理數據訪問權限，並提升資源利用率。
+ 這篇文章清楚地解釋了列級別安全性的概念以及它如何解決實際的資料安全問題，對於需要管理敏感數據的企業來說很有幫助。
+ 範例程式碼說明非常清晰，讓我對 RLS 在 CockroachDB 中的應用有了更深入的瞭解。

N-gated Hacker News🐓 #CockroachDB, the #database that’s as resilient as its namesake, now lets you micromanage #row-level #access because table-level paranoia just isn’t enough. 🎭 You can now play a game of who-can-see-which-row with fine-grained precision—because who doesn’t love spending their time configuring a labyrinth of data permissions? 💼🔒
