One technical question: Is that session information available in the log?
If so, as you have put it, the exact session boundaris could be obtained
and this will nullify many works, :-)


【 在 iamgufeng (古风) 的大作中提到: 】

: roamingo,Which methods did you adopt frequently in your experiments, such as

: : I think it's better to use a configurable variable when you are writing

: : For the second question, there are many, depending on what kind of patterns
