Harshavardhana 8f61d6b6be Move memory code out, add it as layer on top of existing donut code 
Just like how http.Handlers can be overlayed on top of each other
with each implementing ServeHTTP().

drivers.Driver can be overlayed on top of each other in similar manner
which would implement the drivers.Driver interface.

Harshavardhana a4d20d1e75 Merge pull request #685 from harshavardhana/pr_out_add_append_method_to_trove_cache_for_appending_data_to_an_existing_key 
Add Append() method to trove cache for appending data to an existing key
 2015-06-28 03:28:06 +00:00
Harshavardhana 05f8654e3d Add Append() method to trove cache for appending data to an existing key 
This largely avoids a large buffer copy which would accumulate inside proxyReader{}

This patch also implements "initialize()" function to init and populate data
on all the existing buckets, avoiding the redundant ListBuckets() invoked by
every API call.
