I have InnoDB based tables that I can checksum with:

```
checksum table _table_name_

```

That is slow in case millions of records reside in the table. I wonder if there is any way to recognize, whether a table was altered or not?

I needed something that is fast and cheap to request, and changes every time a change is made to any of the records of a table. I do not find anything for InnoDB tables. Is there something?
