    Description

      There are lots of conversion error messages

      error in int conversion from ''
      

      in journalctl output running test001.
      The MCOL-4580 patch replaced string to int conversion method with additional stderr message if conversion has a flaw or failed. The approach didn't take into account two facts: empty string represents VARCHAR NULL value, empty string conversion always fails. The combination of two causes excessive log messages.
      As a temporary solution I will partially revert the original code that existed before MCOL-4580 and create an issue to start TreeNode refactoring in the context of string to integer types conversion.
