# This test is for checking that the use of SQL_SLAVE_SKIP_COUNTER
# behaves as expected, i.e., that it is guaranteed to skip an entire
# group and not start executing in the middle of a transaction.
# We are checking the correct behaviour when using both a
# transactional and non-transactional table. The non-transactional
# table comes into play when rolling back a transaction containing a
# write to this table. In that case, the transaction should still be
# written to the binary log, and the slave will apply it and then roll
# it back to get the non-transactional change into the table.
