-----------------------------------

             Summary: Is it possible to disable caching in kylin?
                 Key: KYLIN-1071
                 URL: https://issues.apache.org/jira/browse/KYLIN-1071
             Project: Kylin
          Issue Type: Improvement
          Components: Query Engine
    Affects Versions: v1.0, v1.1
            Reporter: Shaofeng SHI
            Assignee: hongbin ma
             Fix For: v1.2


This is a requirement from eBay user (internal JIRA: KYLIN-320):

Is it possible to disable caching in kylin? The ideal scenario is passing a parameter when sending a query to kylin and determining if caching should be disabled or enabled. For example, below is a sample command for getting data from Kylin:
curl -b "JSESSIONID=$sessid" -X POST -H 'Content-Type: application/json' -d '
{"sql":"'"$1"'", "offset":0, "limit":100000, "acceptPartial": false, "project":"Nous"}
' http://kylin.corp.ebay.com/kylin/api/query
It will be super helpful if in addition to sqlstatement, offset, limit and acceptPartial we have another parameter which is useCache.
