URL: https://github.com/apache/fluss/issues/2571

   ### Search before asking
   
   - [x] I searched in the [issues](https://github.com/apache/fluss/issues) and 
found nothing similar.
   
   
   ### Description
   
   ```
       public Result applyFilters(List<ResolvedExpression> filters) {
   
           List<ResolvedExpression> acceptedFilters = new ArrayList<>();
           List<ResolvedExpression> remainingFilters = new ArrayList<>();
   
           // primary pushdown
           // (1) batch execution mode,
           // (2) default (full) startup mode,
           // (3) the table is a pk table,
           // (4) all filters are pk field equal expression
           if (!streaming
                   && startupOptions.startupMode == 
FlinkConnectorOptions.ScanStartupMode.FULL
                   && hasPrimaryKey()
                   && **filters.size() == primaryKeyIndexes.length**) {
   ```
   
   The `filters.size() == primaryKeyIndexes.length` is wrong which will cause 
some filter push down fall into the pk lookup code branch, then resuting wrong 
result.
