這份資料探討了資料庫中被稱為「索引囤積」的問題，並警告了多種可能導致資料庫效能下降和儲存空間膨脹的索引配置。 資料來源概述了幾種「囤積」指標，例如單一表格上擁有十個或更多非叢集索引的情況，這通常被認為是過多的。 文件還討論了超過百分之五的非叢集索引未被使用，以及單獨列出未使用的非叢集索引，並說明應如何解讀這些使用統計數據。 此外，來源提醒使用者注意寬索引（包含七個或更多欄位）、多欄位叢集索引，以及非唯一叢集索引對資料庫造成的潛在負面影響。 最後，文件指出了那些寫入次數遠高於讀取次數的非叢集索引，可能是不必要的維護負擔。 -- Hosting provided by SoundOn

ONE Record 是一項用於數據共享的標準，旨在建立一個端對端數位化的物流和運輸供應鏈。其核心目標是實現數據在空運貨運生態系統的利害關係人、社群和數據平台之間輕鬆透明地交換。這透過從點對點傳訊模式轉變為依賴「虛擬貨運記錄」(Virtual Shipment Record) 的數據共享模式來達成。此標準的目標是解決電子貨運的主要挑戰，釋放完全數位化空運貨運產業的可能性，並為新的增值服務和商業模式創造機會。 -- Hosting provided by SoundOn

This discussion dives deep into the escalating tensions between the ideals of open-source software and the harsh realities of geopolitics. The removal of Russian developers from the Linux community underlines the growing conflict between global collaboration and national interests. Russia's response—building an independent Linux fork—sets a precedent for technological sovereignty, prompting concerns about fragmentation within the open-source ecosystem. The ripple effects are profound: China's reevaluation of its reliance on Linux and increased focus on HarmonyOS signifies a global shift towards self-reliance. Meanwhile, open-source principles face a stress test as the community grapples with security concerns, trust, and maintaining interoperability amid rising specialization. This saga raises critical questions: Can open source remain a bastion of collaboration in a fragmented world? Or will these geopolitical fractures drive innovation in unexpected ways? -- Hosting provided by SoundOn
