[GitHub] [incubator-uniffle] frankliee commented on issue #108: [Improvement] `sendCommit` should allow shuffle servers dead under the condition of ensuring data integrity

   These configs are come from quorum protocol.
   `rss.data.replica` is default replica number of partition.
   `rss.data.replica.write` is the minimum replica that writer should write metadata and data successfully. 
   `rss.data.replica.read` is the minimum replica that reader should read metadata successfully (data can read from only one replica). 
   So the recommended values are (1,1,1) and (3,2,2).
    
   These are client-side configs,  and will not change server-side state.
   The flush is controlled by server configs, such as memory capacity and watermarks.
