Amareshwari Sriramadasu commented on LENS-426:
----------------------------------------------
I'm looking at improving logs on estimate path, after looking at one of the
estimate calls, I'm posting the frequent log that comes in the log files. Does
anyone think following logs are too much information and we should reduce?
* Logs to do with denormalized column and its corresponding optional dimension :
{noformat}
27 Jul 2015 08:50:19,465 [estimate-96] INFO
org.apache.lens.cube.parse.DenormalizationResolver - Adding denormalized
column for column:xxxx for table:fact_table
27 Jul 2015 08:50:19,465 [estimate-95] INFO
org.apache.lens.cube.parse.CubeQueryContext - Adding optional dimension:dimx
optDim:CubeQueryContext.OptionalDimCtx(colQueried=[xxxx],
requiredForCandidates=[....], isRequiredInJoinChain=false) for column:xxxx
isRef:true
{noformat}
27 Jul 2015 08:50:32,883 [estimate-95] INFO

Name#start:2011-04-01-00:0.0, type=string,
numOfDistinctValues=Optional.absent()), references=[], isJoinKey=false,
chainName=chainx, refColumn=name), reference=null, srcAlias=rrcube,
pickedFor=fact_table)]
