+.Description
+
+      Should be enabled only if hbase.regionserver.slowlog.buffer.enabled is 
enabled.
+      If enabled (true), all slow/large RPC logs would be persisted to system 
table
+      hbase:slowlog (in addition to in-memory ring buffer at each 
RegionServer).
+      The records are stored in increasing order of time.
+      Operators can scan the table with various combination of 
ColumnValueFilter.

Review comment:
       Generally i feel that the querying will be like for given time range 
give me all the slow logs? Then they can drill down. So if they want to query 
with TS they can specify the Time range correct? Probably you can provide a 
sample input and output for that too.
