wardlican opened a new pull request, #3927:
URL: https://github.com/apache/amoro/pull/3927

   
   ## Why are the changes needed?
   In DefaultTable Service, it is compatible with master-slave mode. In 
master-slave mode, it is necessary to load tables from catalog, determine the 
addition and deletion of tables, complete the allocation of tables to bucketId, 
and the logic of ams nodes loading the tables they are responsible for based on 
bucketId.
   
   Close #3923 .
   
   ## Brief change log
   
   - Add a bucketTableSyncScheduler to DefaultTableService for table loading 
logic in master-slave mode.
   - The history of adding upgrades and switching to master-slave mode is that 
the allocation table is initialized with SQL for bucket allocation.
