查詢計劃是一連串用來存取關聯式資料庫管理系統 (DBMS) 內資料的步驟。DBMS 查詢最佳化程式會選擇一種替代方式來執行特定查詢,但效能落差非常大。由於查詢最佳化程式並不完善,資料庫使用者和管理員有時必須手動檢驗並調整計劃,才能提升效能。如無特定專業知識,為效能資料建立相互關聯可能會花費數小時。 

RDS 績效詳情可讓所有資料庫使用者只花費幾秒,即可在原有的視覺化儀表板上找出最佔用資源的 SQL 查詢。現在,RDS 績效詳情更能收集資源密集 SQL 查詢的查詢計劃,並隨時間加以存放。您可判定 SQL 查詢效能改變是否源自於不同的查詢計劃,您亦可比較新舊查詢計劃,如此可改進應用程式,例如最佳化慢速 SQL 查詢、為資料庫新增索引和擴展資料庫。 

Amazon RDS 績效詳情是 RDS 的資料庫效能調校和監控功能,可讓您以視覺化方式評估資料庫的負載,並判斷採取行動的時機和位置。只要在 Amazon RDS 管理主控台中按一下,您就能為 Amazon RDS 資料庫新增全受管的效能監控解決方案。RDS 績效詳情包含在支援的 Amazon Aurora 叢集和 Amazon RDS 執行個體中,並可在滾動視窗中存放七天的效能歷史記錄,而且無需額外的成本。如果您需要長期保留,可選擇付費以最長保留兩年的效能歷史記錄。 

AWS 對 Internet Explorer 的支援將於 07/31/2022 結束。支援的瀏覽器包括 Chrome、Firefox、Edge 和 Safari。 進一步了解 »
