Next, the filtering operations are executed in parallel on each TiFlash node for the `order` and `product` tables. The filtering conditions are `SUBSTR(order.dic, 3) = '7c0'` for the `order` table and `product.pct_date > '2021-09-30'` for the `product` table, as shown in the slide. The filtered data is then stored in the memory of the TiFlash nodes.
