Description
** (flashback:5846): WARNING **: option parsing failed: Integer value '3122794731' for --stop-position out of range
对于一些大表来讲，超过2GB的binlog position挺常见的，目前MyFlash仅支持int32的position

Research direction
Start by tracing --stop-position option parsing and the integer representation used for MySQL binlog positions, reproducing the reported value 3122794731. Done means MyFlash accepts positions above the signed 32-bit maximum without reporting an out-of-range parsing warning.
