in case of disk failure,why not recover from middle position of the log file

can we write the byte position of .log 、.index file to a position-checkpoint file, and recover from the position to rebuild the index files?

Hi Zhang,

Yes, when doing log recovery, we'll start from the checkpoint for the
partition in `recovery-point-offset-checkpoint` file, which will be updated
at runtime. Is that what you expected?

Check LogManager#loadLogs method for more implementation detail.

Thanks.
Luke
