dockerzhang opened a new issue #1180:
URL: https://github.com/apache/incubator-inlong/issues/1180


   <p>Based on the consideration of removing the BDB, we will extract the 
metadata and the active/standby keep-alive logic (completed by issue <a 
href="https://issues.apache.org/jira/browse/TUBEMQ-570"; class="external-link" 
rel="nofollow">https://issues.apache.org/jira/browse/TUBEMQ-570</a>), and then 
migrate to Zookeeper-based metadata storage and active/standby keep-alive 
(completed by issue <a href="https://issues.apache.org/jira/browse/TUBEMQ-567"; 
class="external-link" 
rel="nofollow">https://issues.apache.org/jira/browse/TUBEMQ-567</a>).</p>
   
   <p>The Zk interaction logic of TubeMQ adopts the early implementation of 
HBase. Considering the cleanliness of the code, users who have a deeper 
understanding of ZK interaction can try to reconstruct this piece of business 
logic to provide better metadata storage and master Implementation of the 
interface for standby switching (the relevant interface abstraction is defined 
on the metamanage module of the branch <a 
href="https://issues.apache.org/jira/browse/INLONG-570"; title="Optimizing the 
implementations of HTTP API for Master" class="issue-link" 
data-issue-key="INLONG-570">TUBEMQ-570</a>)</p>
   
   <p>This part is very difficult and requires experienced students to analyze 
and check it. Before actually doing it, many discussions are needed to confirm 
whether there is a better approach.</p>
