Jonathan Gray updated HBASE-1249:
---------------------------------
Attachment: HBASE-1249-GetQuery-v1.pdf
This is somewhat related to HBASE-880, but specifically talks about how we will
implement Gets on the server-side.
For each GetX object we have on the client, there will be a corresponding
GetXServer object that will contain any necessary state for processing the
request. In addition, the GetServer interface will include a very unique and
specialized compareTo(KeyValue) method with a range of return values [-1, 4] as
described in the doc.
These GetServer implementations will be where all the specialized server-side
logic will live that allow the different styles of gets to be done in an
optimized way. The bulk of that logic lives in the column/timestamp comparison
in the compareTo.
More information and examples to follow.
