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.

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.，推荐阅读新收录的资料获取更多信息
