Just wanted to let you know I found the cause. They’re using the UUID() function which doesn’t yet work in replication.

Have a good weekend!

Thanks for your time, Baron!

MD5(col) = MD5(col)…

Trailing spaces are stripped from comparisons so SQL joins may not agree with the checksums.

I have an interesting problem (?) with mk-table-checksum

Using BIT_XOR it shows the tables are different.

Doing a SQL comparison shows them the same. I know we can expect different results with doubles and/or floats, but this table has neither.

Table layout and comparison shown below:
