   i meet the same issue
   its cost too much time to load too many default tables like 5000+
   i just make the initializer skipped load the default table meta data by only create new 
   dont know what would happen
   and the switch **check.table.metadata.enabled** cant solve this issue
   
   
   ```
       public TableMetaData load(final String logicTableName, final ShardingRule shardingRule) throws SQLException {
           if(!isCheckingMetaData){
               return new TableMetaData(new ArrayList<ColumnMetaData>());
           }
           List<TableMetaData> actualTableMetaDataList = load(getDataNodeGroups(logicTableName, shardingRule), shardingRule.getShardingDataSourceNames());
           checkUniformed(logicTableName, actualTableMetaDataList);
           return actualTableMetaDataList.iterator().next();
       }
   ```
