Todd Lipcon commented on HBASE-7474:
------------------------------------
What's the advantage of doing this, server side?
Server-side filtering and server-side aggregation make sense, because it
reduces the amount of data that has to be read over the network. But, a server
side sort will transfer the same amount of data - it just moves extra CPU cost
from the client to the server, which IMO seems like the wrong direction.

> Recently, i have developed an Endpoint which can sort the Results(rows) on
> the basis of column values. This functionality is similar to "order by"
> clause of RDBMS. I will be submitting this Patch for HBase0.94.3
> I am almost done with the initial development and testing of feature. But, i
> need to write the JUnits for this. I will also try to make design doc.
