Parsing mode-stop-never continuously synchronizes binlog. Optional. Add or synchronize to the latest binlog location when the command is executed. -K,-- no-primary-key removes the primary key from the INSERT statement. Optional. -B,-- flashback generates a rollback statement that parses large files without memory restrictions, adding a SLEEP SELECT (1) for every thousand lines printed. Optional. Cannot be added at the same time as stop-never or no-primary-key.

Parsing scope control-start-file starting parsing file. Must. -- the starting resolution position of the start-position/--start-pos start-file. Optional. The default is the starting position of start-file. -- parse the file at the end of stop-file/--end-file. Optional. The default is start-file the same file. If the parsing mode is stop-never, this option has no effect. -- the parsing position at the end of the stop-position/--end-pos stop-file. Optional. The default is the last location of stop-file; if the parsing mode is stop-never, this option has no effect. At which point in time does the start-datetime begin to be parsed by binlog, and the format must be datetime, such as' 2016-11-11-11-11-11-11-11-11-11-1-1-1-11-11-11 / 11 / 11 / 11 / 11 / 11 / 11 / 11 / 11 / 11 / 11 Optional. Does not filter by default. At which point in time does the binlog of stop-datetime stop parsing? the format must be datetime, such as' 2016-11-11-11-11-11-11-11-11-11-11-11-1-1-11-11 / 11 / 11 / 11 / 11 / 11 / 11 / 11 / 11 / 11. Optional. Does not filter by default.

Object filtering-d,-- databases outputs only the sql of the target db. Optional. The default is empty. -t,-- tables outputs only the sql of the target tables. Optional. Default is empty
