   ## Proposed changes
   Issue Number: close #35024 
   This bug is because the fe incorrectly sets the update time of paimon 
catalog, causing the be to be unable to update paimon's schema in time.
   ```c++
       private void initTable() {
           PaimonTableCacheKey key = new PaimonTableCacheKey(ctlId, dbId, 
tblId, paimonOptionParams, dbName, tblName);
           TableExt tableExt = PaimonTableCache.getTable(key);
           if (tableExt.getCreateTime() < lastUpdateTime) {
               LOG.warn("invalidate cache table:{}, localTime:{}, 
remoteTime:{}", key, tableExt.getCreateTime(),
                       lastUpdateTime);
               PaimonTableCache.invalidateTableCache(key);
               tableExt = PaimonTableCache.getTable(key);
           }
           this.table = tableExt.getTable();
           paimonAllFieldNames = 
PaimonScannerUtils.fieldNames(this.table.rowType());
           if (LOG.isDebugEnabled()) {
               LOG.debug("paimonAllFieldNames:{}", paimonAllFieldNames);
           }
       }
   ```
