    Description

      If a read is performed in two parts due to short read protection, and the data being read is written to between reads, the coordinator will return a partial update. Specifically, this will occur if a single partition batch updates clustering values on both sides of the SRP break, or if a range tombstone is written that deletes data on both sides of the break. At the coordinator level, this breaks the expectation that updates to a partition are atomic, and that you can’t see partial updates.
