Reviewer: Marcus Eriksson
> ByteBuffer write() methods for serializing sstables
> ---------------------------------------------------
>
> Key: CASSANDRA-6781
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6781
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Benedict
> Assignee: Benedict
> Priority: Minor
> Fix For: 2.1 beta2
>
>
> As mentioned in CASSANDRA-6689, there may be some performance issues with
> writing sstables from offheap memtables. This is mostly plausibly caused by
> the single-byte-at-a-time write path for ByteBuffers, as we use DataOutput
> which only accepts byte[].
> I propose extending DataOutput to include ByteBuffer methods, and to use this
> extended interface for serializing sstables instead.
