For the Filling: Adjust oven rack to lower middle position and preheat to 400°F (205°C). In a large bowl, whisk together sugar, tapioca starch, salt, cinnamon, and baking soda until well combined. Add berries and toss to coat. Scrape into a 7- by 11-inch glass, ceramic, or stoneware baking dish (do not use metal) and set aside while you prepare the topping.
