Claim 3:
4. The system according to claim 3, wherein,
the CS is further configured to request a field value globally incremented in service from each of the plurality of CCs;
each of the plurality of CCs is further configured to search from a binlog starting position in the F environment until a first binlog position not less than the field value is found, and return a field value corresponding to the first binlog position to the CS;
the CS is further configured to take a maximum field value as an initial field value after collecting the field value returned by each of the plurality of CCs, query the memory database to obtain a corresponding initial field value of the T environment corresponding to the initial field value according to the mapping relationship between the message values of the T environment and the F environment, and issue the initial field values of the T environment and the F environment to all the CCs;
each of the plurality of CCs is further configured to obtain a binlog file and position corresponding to the initial field values of the T environment and the F environment, and return the binlog file and position to the CS;
the CS, after receiving the binlog file and position, notifies all the CCs to start parsing the binlog by batch;
each of the plurality of CCs is further configured to parse the binlog by batch, replace a value that has a correspondence between the F environment and the T environment with a value of the T environment, and return a parsing result; and
the CS generates a generation file and performs a comparison after receiving a parsing result of a batch, and stores a comparison result in the result database.
