After setting up streaming replication, is it possible to check whether the slave has the same data as the master?

In the MySQL world there is the percona-toolkit with pt-table-checksum that does this job:

Thank you

I have not digged to deep, but as far as I can see from your link:

pt-table-checksum requires statement-based replication, and it sets binlog_format=STATEMENT on the master

And the mysql manual says

If you are using InnoDB tables and the transaction isolation level is READ COMMITTED or READ UNCOMMITTED, only row-based logging can be used.

So, if I am not misinterpreting, this plays in a different league.
