Choose a Database: Cloud Firestore or Realtime Database

原文在這

Firebase提供了以下2種給支援clinet端存取與資料即時資料同步的雲端資料庫

• Realtime Database

Realtime Database是Firebase一開始推出的資料庫，對於需要資料即時同步的APP，Realtime Database是一個擁有高效能且低延遲的解決方案

is Firebase's original database. It's an efficient, low-latency solution for mobile apps that require synced states across clients in realtime.

• Cloud Firestore

Cloud Firestore是Firebase對mobile app開發所推出的新版旗艦資料庫，Cloud Firestore站在前人(Realtime Database)的肩膀上，採用了更直覺的資料模型，以及比Realtime Database更豐富與快速的搜尋與擴展功能。

is Firebase's new flagship database for mobile app development. It improves on the successes of the Realtime Database with a new, more intuitive data model. Cloud Firestore also features richer, faster queries and scales better than the Realtime Database

Which database is right for your project?

如果你滿意beta版本的Cloud Firestore，將它應用在你的新專案上吧。Cloud Firestore在未來將釋出基於現在的功能與架構，提供更好的效能、擴充性
