-----------------------------------
Resolution: Incomplete
Incomplete dead issue
> Use of Serializable in IPC makes an unnecessary copy
> ----------------------------------------------------
>
> Key: HBASE-4807
> URL: https://issues.apache.org/jira/browse/HBASE-4807
> Project: HBase
> Issue Type: Improvement
> Components: io, IPC/RPC
> Affects Versions: 0.92.0
> Reporter: Todd Lipcon
> Priority: Minor
>
> This code path isn't used much, but in HbaseObjectWritable, the code to
> serialize and deserialize Serializables makes an unnecessary copy through
> ByteArrayOutputStream.toByteArray. Instead we could use DataOutputBuffer,
> perhaps.
