Jaskey Lam commented on ROCKETMQ-245:
-------------------------------------
I am afraid this design is with careful consideration, which helps to improve
the write performance when topic is at great numbers.
This is a great improvement when topic numbers is large comparing to Kafka.
> All topic msg put in the same log may is not a good desgin .

> Priority: Minor

> The MQ put all topic msg in the same log file . I think is not a good design .
> Reason : all topic concurrency put msg , they need compete for one file lock,
> topic may influence each other .
> Some one have change topic msg to store in independent file . The QPS is
> high than store in the same log file ( The store log system is still include
> physic log and queue .)
