Jonathan Ellis updated CASSANDRA-3163:
--------------------------------------
Attachment: 3163-v2.txt
v2 re-clones into indexposition instead of trying to avoid cloning at all.
this should be a small penalty since we're only re-cloning sampled keys, not
all of them.
> SlabAllocator OOMs much faster than HeapAllocator
> -------------------------------------------------

> Key: CASSANDRA-3163
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3163
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.0
> Environment: 3 nodes, 1G heap, RF=2
> Reporter: Brandon Williams
> Fix For: 1.0

> Attachments: 3163-v2.txt, 3163.txt, system.log.gz

> SlabAllocator will OOM with stress at around 5.5M rows, which in this
> configuration is roughly 3.3M rows per node. Reverting to the HeapAllocator
> allowed all 10M rows to finish. Examining the SA heap dump in MAT just shows
> ~98% of the heap is in 'remainder'
