In my case, related information is like this. Kylin version: 1.5.2 HBase version: HBase 0.98.4.2.2.9.0-3393 Cube size: 13.16GB Source records: 85,794,927 Dimension number: 20 (several joint groups) Measure type: bigint SQL query: select count(distinct userid) from XXX LIMIT 50000
If you need more information please let me know. -----Original Message----- From: ShaoFeng Shi [mailto:shaofeng...@apache.org] Sent: Tuesday, June 21, 2016 10:51 PM To: dev@kylin.apache.org;

re-produce it in our side first; If you can provide more information about your case (like hbase version, cube size, dimension nubmer, measure type, SQL query, etc), that would be great! 2016-06-20
