+Significant changes have taken place in metadata and cube data, upgrade from v1.3 and before is difficult. Recommend build new cube from scratch with this version.
__Highlights__
- * [KYLIN-875] - A plugin-able architecture, to allow alternative cube engine / storage engine / data source.
- * [KYLIN-1245] - A better MR cubing algorithm, about 1.5 times faster by comparing hundreds of jobs.
- * [KYLIN-942] - A better storage engine, makes query roughly 2 times faster (especially for slow queries) by comparing tens of thousands sqls.
- * [KYLIN-738] - Streaming cubing EXPERIMENTAL support, source from kafka, build cube in-mem at minutes interval.
- * [KYLIN-242] - Redesign aggregation group, support of 20+ dimensions made easy.
- * [KYLIN-976] - Custom aggregation types (or UDF in other words).
- * [KYLIN-943] - TopN aggregation type.
- * [KYLIN-1065] - ODBC compatible with Tableau 9.1, MS Excel, MS PowerBI.
- * [KYLIN-1219] - Kylin support SSO with Spring SAML.
