-------------------------------------

             Summary: Optimize the implementation of RmtDataCache class
                 Key: TUBEMQ-585
                 URL: https://issues.apache.org/jira/browse/TUBEMQ-585
             Project: Apache TubeMQ
          Issue Type: Improvement
          Components: Client
            Reporter: Guocheng Zhang


This class is used by the consumer to cache and manage metadata: the heartbeat from the client to the Master will update the cached metadata; the consumption request and response will query the metadata, and clean up the abnormal partition when it is abnormal. It belongs to the type to read more and write less, need to control concurrent access.

 

The implementation of it is not very good personally: it uses too many ConcurrentHashMap structures. If the implementation is optimized and adjusted while keeping the functions unchanged, the readability and operating efficiency of this part should be better.

 

The difficulty of this part is average, if someone has a better approach, welcome to put forward your ideas and communicate and improve it together.
