+
+## Context

+- Client always make requests to back-end to refresh the data, what put a lot of pressure on it.
+- User need to wait a long time to see the mailbox and email.
+
+## Decision
+
+- Caching the data with the [Hive](https://github.com/hivedb/hive) dependencies 
+Hive is a lightweight and blazing fast key-value database written in pure Dart. It support cross-platform: mobile, desktop and browser
+
+- `changes` method allows a client to efficiently update the state of data (Mailbox and Email)
+
+## Consequences
+
+- Minimizing the requests to the back-end 
+- Reducing the latency in the client
+
+## Follow up works
+
+- Pre-loading the bodies of the some latest unread messages
