> 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.
