A total of 4 table have been compared and all are equal.

-------------------------------------------------------------

The command will eventually output the check report summary.txt and log sync_diff.log for this comparison in the output-dir output directory in config.toml. A folder named by a hash of the config.toml file contents is also generated in the output directory, which contains the checkpoint node information for the breakpoint resume and the SQL fix data generated if the data is inconsistent.
