> Reuse byte buffers in AsyncRpcClient
> ------------------------------------
>
> Key: HBASE-15491
> URL: https://issues.apache.org/jira/browse/HBASE-15491
> Project: HBase
> Issue Type: Improvement
> Components: Client
> Affects Versions: 2.0.0
> Reporter: Vladimir Rodionov
> Assignee: Vladimir Rodionov
> Attachments: HBASE-15491-v1.patch
>
>
> IPCUtil.buildCellBlock is used by both server and client. Server provides
> BoundedByteBufferPool for buffers reuse, client code does not do that. This
> results in additional memory pressure on a client side, because buffers are
> allocated on every call to IPCUtil.buildCellBlock.
> My own local tests (with patch) show approximately 8-10% reduction in object
> allocation rate on a client side (with HBASE-15479 as well).
