Made from natural materials like biodegradable plastics, recycled ocean waste or even sustainable bamboo, eco-friendly phone cases and compostable phone covers prove that you don’t have to sacrifice style or protection to make the greener choice. Whether you’re looking for something sleek and minimal or bold and artistic, there are a number of eco-friendly options to choose from. And remember, even if you can't find a sustainable phone case that fits all your requirements, any phone case that allows you to get a few more years our of your smartphone instead of buying new and upgrading is eco-conscious in itself.

Lightweight updates take a fundamentally different approach. Instead of rewriting entire data parts, a lightweight update creates a small, compact "patch part" containing only the changed column values and metadata to locate the affected rows. These patches are applied on-the-fly during reads (so changes are visible immediately) and materialized efficiently during regular background merges — piggybacking on work ClickHouse is already doing. This can be up to 1,000× faster than classic mutations for many workloads. The same mechanism can be used for deletes, which set a _row_exists = 0 mask via a patch part rather than rewriting columns. For a deep dive into how patch parts work, see our series on fast UPDATEs in ClickHouse: Part 1 — purpose-built engines and Part 2 — SQL-style updates.
