Kylin Architeccture
Hi All,
Please give me low level architecture of Kylin.
My question is why Kylin use Hbase and Hive both in Hive I know its using
for source system but why Hbase?
In case of cube building does kylin pre-aggregate the data or when I query
to Kylin cube its calculating in runtime?
Best Regards,
ANKIT BEOHAR

Yes.
Kylin leverages HBase as internal storage system.

Why HBase...hbase is native on Hadoop KV system.
HBase is most balance one for Kylin use case, especially when you deploy a
dedicated hbase for Kylin (it's read only cluster).
Would you mind to share with community why you are concerning about HBase
as storage?
Thanks.
Luke
