Benedict commented on CASSANDRA-9932:
-------------------------------------

Hmm. I filtered that out because I knew the related code hadn't changed since 
it was first written, and I knew it failed due to OOM.

It is completely benign and a test failure, however (and if you fix it, it 
still fails against default heap with OOM). It simply requires a non-null 
{{UpdateFunction}}. I've fixed, pushed, and am running a lengthy burn test run 
for security.

> Following on from the other btree related refactors, this patch makes all 
> partition (and partition-like) objects backed by the same basic structure: 
> {{AbstractBTreePartition}}. With two main offshoots: 
> {{ImmutableBTreePartition}} and {{AtomicBTreePartition}}
> The main upshot is a 30% net code reduction, meaning better exercise of btree 
> code paths and fewer new code paths to go wrong. A secondary upshort is that, 
> by funnelling all our comparisons through a btree, there is a higher 
> likelihood of icache occupancy and we have only one area to focus delivery of 
> improvements for their enjoyment by all.
