+## Processing big sets of data ( filtered records )
+
+There might be cases when you want to process more records than can fit your list view.
+Here you can use the `recordSelector` param.
+It can be `checkbox` (default) or `filtered`.
+`filtered` uses all filtered records for generation, so you can even process the whole resource.
+
+
+```ts
+        new BulkAiFlowPlugin({          
+          actionName: 'Generate description and Price',
+
+          //diff-add
+          recordSelector: 'filtered', // default is 'checkbox'
+
+          ...
+
+        });
+```
+>❗️❗️❗️ Using `recordSelector: 'filtered'` might be expensive. Before processing large data sets, we recommend starting with smaller sets to make sure everything is fine.
+
+
+## Limiting amount of parallel requests using p-limit
+
+If you are processing large sets of data, you might want to limit the number of parallel requests. For this, you can use the `concurrencyLimit` param:
+
+```ts
+        new BulkAiFlowPlugin({          
+          actionName: 'Generate description and Price',
+
+          //diff-add
+          concurrencyLimit: 5, //default is 10
+
+          ...
+
+        });
+```
+
+And there won't be more than 5 parallel requests being handled.
