[enhancement] ​​Logging Optimization

[haohao0103]

Search before asking

• [x] I searched in the issues and found nothing similar.

Motivation

Two main optimizations were implemented:

1. No log level check was performed when invoking LOG.warn(xx);
2. Log statements did not use placeholders;

Solution

1. add DEBUG-level log checks before logging operations;
2. log statements use parameterized placeholder

Anything else?

NONE
