Blake Eggleston commented on CASSANDRA-14517:
---------------------------------------------

Not sure there's much that can be done about this that would be reasonable. 
There might (_might_) be a way to fix this for SRP, but paging has the same 
issue

> Short read protection can cause partial updates to be read

> 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.
