 The maximum allowed limit is 50,000 rows. You can use the `CUBEJS_DB_QUERY_LIMIT`
 environment variable to override it. You can also implement
 [pagination][ref-pagination-recipe] to fetch more rows than the maximum limit.
+Finally, if you're using the [SQL API][ref-sql-api], you can enable the
+[streaming mode][ref-sql-api-streaming] to ignore the maximum row limit.
