The Percona Toolkit includes a tool called pt-table-checksum that enables you to compare databases on different databases using a checksum comparison. This can be executed by running the checksum generation process on the Primary:

shell> pt-table-checksum --set-vars innodb_lock_wait_timeout=500 \
    --recursion-method=none \
    --ignore-databases=mysql \
    --ignore-databases-regex=tungsten* \
    h=localhost,u=tungsten,p=secret

Using MySQL, the following statement must then be executed to check the checksums generated on the Primary:

mysql> <userinput>SELECT db, tbl, SUM(this_cnt) AS total_rows, COUNT(*) AS chunks \
    FROM percona.checksums WHERE ( master_cnt <> this_cnt OR master_crc \
    <> this_crc OR ISNULL(master_crc) <> ISNULL(this_crc)) GROUP BY db, tbl;</userinput>

Any differences will be reported and will need to manually corrected.
