### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) ### Search before asking - [X] I have searched in the [issues](https://github.com/apache/incubator-uniffle/issues?q=is%3Aissue) and found no similar issues. ### What would you like to be improved? In ComposedClientReadHandler, storage tiers are represented in int values, and it uses a lot of switch-case to get the corresponding handler. This is error prone and difficult to understand. ### How should we improve? Represent storage tier as enum, and get handlers by EnumMap. ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! -- This is an automated message from the Apache Git Service.
