Hi team, I have faced problem about query performance on Kylin. I run two instance Kylin(job) and Kylin(query) on two node of my hadoop cluster.
When my cluster have high load, it make kylin query running slow. I think high load affect to Hbase so that it make kylin read data from Hbase slower. But When my cluster have normal load (average below 10% CPU). I login Kylin and test one query, It always slow on first time. When I repeat this query again, I see it's faster. I test with a lot of queries, but it's always slow on 1st try. I wonder Do Kylin have slower when open connection and faster after that ? If not So any solution to fix my issue?
