> Avoid building PartitionUpdate in toString()
> --------------------------------------------
>
> Key: CASSANDRA-10897
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10897
> Project: Cassandra
> Issue Type: Bug
> Components: Coordination
> Reporter: Tyler Hobbs
> Assignee: Tyler Hobbs
> Priority: Minor
> Fix For: 3.0.x, 3.x
>
>
> In {{AbstractBTreePartition.toString()}} (which {{PartitionUpdate}} extends),
> we iterate over the rows in the partition. This triggers {{maybeBuild()}} in
> the {{PartitionUpdate}}. If the {{PartitionUpdate}} gets updated after the
> {{toString()}} call, it will result in an {{IllegalStateException}} with the
> message "An update should not be written again once it has been read".
> As a result, logging or using a debugger can trigger spurious errors, which
> makes debugging difficult or impossible.
