Subject [jira] [Commented] (CASSANDRA-6781) ByteBuffer write() methods for serializing sstables
Date Wed, 19 Mar 2014 13:30:45 GMT


Marcus Eriksson commented on CASSANDRA-6781:

this looks good to me, rebased, squashed and pushed;
- with a small commit on top, mostly removing unused imports and files

>          Issue Type: Improvement

>             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.
