   The function update the latestTime of the table with the latest partition time, I suggest getVisibleVersionTime() and getVisibleVersion() in the same partition.
   ```    
       private CacheTable getLastUpdateTime(OlapTable olapTable) {
           CacheTable table = new CacheTable();
           table.olapTable = olapTable;
           for (Partition partition : olapTable.getPartitions()) {
               if (partition.getVisibleVersionTime() >= table.latestTime &&
                       partition.getVisibleVersion() > table.latestVersion) {
                   table.latestPartitionId = partition.getId();
                   table.latestTime = partition.getVisibleVersionTime();
                   table.latestVersion = partition.getVisibleVersion();
               }
           }
           return table;
       }
   ```
