Kannan Muthukkaruppan updated HBASE-4542:
-----------------------------------------
Description:
Slow query log doesn't report filters in effect.
For example:
{code}
(operationTooSlow): \
{"processingtimems":3468,"client":"10.138.43.206:40035","timeRange":
[0,9223372036854775807],\
"starttimems":1317772005821,"responsesize":42411, \
"class":"HRegionServer","table":"myTable","families":{"CF1":"ALL"]},\
"row":"6c3b8efa132f0219b7621ed1e5c8c70b","queuetimems":0,\
"method":"get","totalColumns":1,"maxVersions":1,"storeLimit":-1}
{code}
the above would suggest that all columns of myTable:CF1 are being requested for
the given row. But in reality there could be filters in effect (such as
ColumnPrefixFilter, ColumnRangeFilter, TimestampsFilter() etc.). We should
enhance the slow query log to capture & report this information.
