Date Thu, 21 Feb 2013 19:36:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7898?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13583470#comment-13583470

stack commented on HBASE-7898:

Working on this issue, did some study of rpc.  Here are findings, why some decisions, and
list of TODOS: https://docs.google.com/document/d/1WCKwgaLDqBw2vpux0jPsAu2WPTRISob7HGCO8YhfDTA/edit#

Here is a specification for wire-format: https://docs.google.com/document/d/1-1RJMLXzYldmHgKP7M7ynK6euRpucD03fZ603DlZfGI/edit#
  Needs polish but basically there. This can be used to get high-level picture when trying
to situate the patches that will be coming in as subtasks of this jira.

> This issue replaces the juicy HBASE-7233 which started undoing KeyValue as a Writable
and ended up as a general discussion of KeyValue serialization. Along the way it served as
a scratch sheet for how to do lots of KeyValues across RPC.  This issue is the umbrella issue
for making it so we can pass Cells over our protobuf'd RPC rather than KeyValues; i.e. an
Interface which could be differently implemented rather than our current non-evolvable KeyValue
