hello hongxi,

After sending an email to dev-subscription, you should have received a
response email asking you to confirm. Just reply that email will finish the
subscription.

For your question, Kylin build the source data to OLAP cube, which only has
aggregated data, no detail data. So if you run a "select * from" query,
actually Kylin couldn't answer; As a workaround, Kylin uses the most-fine
granularity aggregation data answered the query, and for the measure, it
just uses null to represent. If you run an aggregation query (with group
by), it will work as expected.

Best regards,
