Kylin is the OLAP on Hadoop. OLAP is the read-only query engine. So we suppose there is no update/delete operator directly. Kylin support build incrementally. So if new data is ingested, you could build new one(new time range). If you want to update existing cube since the underline data changed, please click "Refresh" on the Cube.
