Description

In some cases, one might be interested in asserting that tables are "equal" under some match rates < 100%. In that case, the tables are of course, no longer equal. In my case, there is data coming from two different streams that should match, but doesn't to 100%, so I'd like to assert it matches at least x%,

I'm not sure yet whether other projects have such a use case as well, but we can use this issue to monitor and discuss it.
