------------------------------------
Summary: More efficiently build IPC responses
Key: HADOOP-13426
URL: https://issues.apache.org/jira/browse/HADOOP-13426
Project: Hadoop Common
Issue Type: Sub-task
Reporter: Daryn Sharp
Assignee: Daryn Sharp
The call response buffer is allowed to dynamically grow until a max size is
reached. Often times the full size of the response can be known in advance
which avoids copies. This is very advantageous for large responses.
Automatic framing of the response buffer will also prevent unnecessary
allocations and copies when the size is/isn't known.
