[fix](scanner) Fix incorrect _max_thread_num in scanner context #40569

zhiqiang-hhhh · 2024-09-09T15:12:45Z

Minor refactor for scanner constructor, calculation of _max_thread_num is moved to init method
The expected value of _max_thread_num is changed. There is no need to submit too many scan task to scan scheduler, since thread num is limited.
Calculation of _max_bytes_in_queue is changed. _max_bytes_in_queue for each scan instance is limited to 100MB by default.

可能把，这个参数，作为scanner context的构造函数的参数，传递给scanner context，这样你往2.1 pick的时候会比较方便。否则2.1 在多种pipeline 模型下，代码不好pick
