zhuangchong opened a new issue #5918:
URL: https://github.com/apache/dolphinscheduler/issues/5918
**Describe the question**
1. When the log is printed using string splicing, when the program judges
the level of the print log, it will splice the log information of the string
first. If the sentence does not print the string in the end, then this spliced
string The process is a meaningless operation, which will increase the loss of
system performance. At this time, it is recommended to use
logger.isDebugEnabled()
2. Use the {} placeholder to print the log, there is no need to prejudge the
level of the log, the bottom layer has already implemented this step.
The current system uses {} placeholders to print logs, so remove the code
logger.isDebugEnabled().
**What are the current deficiencies and the benefits of improvement**
- Repeated calls to determine whether it is debug log level
**Which version of DolphinScheduler:**
-[dev]
