it doesn't fix the threshold, the method name renamed, I think it takes less than 100 right? The actual fix is how to calculate rowcounts. |

Rationale for this change
The fuzz tests for filtered SMJ introduced in #10728 has a flaw when calculating the rowcounts, it fact it caculcated batches which are not always the same and led to false negatives.
