zuston opened a new pull request, #435: URL: https://github.com/apache/incubator-uniffle/pull/435
### What changes were proposed in this pull request? To support multiple disk selection for one partition when using local storage 1. Introduce the `ChainableLocalStorage` to manage the chainable local storage usage for one partition, which is the wrapper of multiple different local storages. The new local storage will be selected only when the storage can't write. 2. Introduce the `LocalFileClientReadMultiFileHandler` to manage multiple handlers, every handler is bound to every disk's data file and index file. By the way, if having this abstract layer, I will introduce the `PooledLocalStorage` to support concurrent writing for one partition like #396 to speed up local disk writing in the future. ### Why are the changes needed? ### Does this PR introduce _any_ user-facing change?
