Will query go through query cached result (of D1,D2,D3) or runs a query on
HBase Table?
P.S. I am using Apache Kylin v2.5.1-hbase1.x
Thank You,

Thanks JiaTao for response. I have upgraded Kylin to v2.5.1-hbase1.x and
issue resolved.

Please correct me if I am wrong.

scanning rows from HBase at coprocessor end.
This also clarified me importance of order of the dimensions in the
rowkey.

Hi Team,
With Kylin v2.4, I have noticed roll up rate is 100.59% ( at level 1
cuboid). Is this issue already filed in JIRA? Below is reference screen
shot.

Hi Team,
In one of our use case, we need to have data encrypted on disk.
Is there any feature which can help us to encrypt cube's data on HBase?
If yes, would you please share reference docs/JIRA links?
P.S. We are using Kylin v2.4
Thank You,
Shrikant Bang.
You,
Shrikant Bang.

nces in tuning "fact distinct column" job for
those reducer which have high cardinality. I am trying with increasing
memory as of now as partitioning and number of reducers are depends on
cuboids number.
P.S. I am using v2.4 of Kylin with HBase 1.x
Thank You,

2. Refresh Settings:
How to specify partition column and format while building cube for fact
table.
e.g. user_activity is partitioned by date '-MM-dd' and cube should
be refreshed everyday with previous day's computation.
