Hi, We are experimenting upgrading our kafka service from 0.10.2 to 1.0.1, and noticed that it was slow in restarting the broker after updating the kafka binary. On a test cluster that have ~120G data on each broker, it took about 20 minutes to load log segments. I am wondering if there is any work-around to reduce the long log segment loading time. Can we manually generate snapshot files to speed up the segment loading? Based on the sever logs, it is also not clear to me between `loadSegments()` and ` loadProducerState(...)` ,which one took more time during the log segment loading.
Thanks! Regards, -Yu
