-------------------------------------

             Summary: Eliminate expensive string creation in debug log messages
                 Key: HDDS-5383
                 URL: https://issues.apache.org/jira/browse/HDDS-5383
             Project: Apache Ozone
          Issue Type: Improvement
            Reporter: Wei-Chiu Chuang


Use IntelliJ and search with regex pattern: LOG\.debug.*toString

I found a number of bad log message practice where string objects are created or concatenated regardless log level.

Parameters passed to slf4j debug log are supposed to be O(1).
