-    The preview of the `join` operator works with an upper limit of 5,000 events on the left side of the join and 50,000 on the right side of the join.
+    The preview of the `join` operator works with variable limits depending on the structure of your dataset. For the left side of the join, the limit is 50,000 rows when the dataset has fewer than 100 fields. This limit decreases linearly as the field count increases: 25,000 rows at 200 fields, 12,500 rows at 400 fields, and 10,000 rows at 500+ fields. The right side of the join has a consistent limit of 50,000 rows.
