C. Scott Andreas updated CASSANDRA-14517:
    Component/s: Coordination

> Short read protection can cause partial updates to be read

>                 Key: CASSANDRA-14517
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14517
>             Project: Cassandra
>          Issue Type: Bug
>          Components: Coordination
>            Reporter: Blake Eggleston
>            Priority: Major
>             Fix For: 4.0
> 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.
