      I found the following logging issues:

      1. premature toString() invocation 
        LOGGER.debug(record.toString());
      2. string concatenation 
        LOGGER.debug("key: " + keyDoc.toString());

      which may cause performance issues in high-load applications.

      In particular, I encountered unnecessary pressure on GC due to the premature toString() invocation.
