Summary: Support fixedLength encoding for TopN measure

Hello,
Need clarification on one point. From what I understand the int value
for the bitmap is per cell ?
As long as the maximum disctinct count for one cell (a given value for
each dimension in the particular cuboid) does not exceed int value we
should be okay ?

Yes, we will be filing a whole bunch of JIRAs. This release is not Done,
so no point in arguing about whether it is perfect. Luke, I do not want
you to push this release through.

Hi Seshu,
"Done is better than Perfect" is one practice in our development:
release early, ask users
to try and test, then fix bugs, bring other features if any, and then
release a new one...
It works very well in the past and I believe it will continue benefit
further development.

Implementing the old MR engine on the pluggable architecture does not prove
that the architecture works. You need two points to draw a line. A single point
does not prove that the architecture works.
Improving the MR engine performance can be done on 1.0 code are without making
it plugg
Seshu's understanding of the 2.0 and its plugin-able architecture is very
wrong. Let me correct. :-)
The plugin-able architecture is rock solid. Its first commit went back to
Jul 2015. On top it, we built MR cube engine V2 and storage engine V2,
which give much improved build and query performance
Resolved the issue . There was some configuration missing in
kylin_job_conf.xml file .

A strong -1 on this.
- A better MR cubing algorithm, about 1.5 times faster than 1.x by
comparing hundreds of jobs.
- TopN pre-calculation (more UDFs coming)
- ODBC compatible with Tableau 9.1, MS Excel, MS PowerBI
These are incremental enhancements and does not warrant bumping up to 2.0

Hi Abhilash,
Any data model change will require rebuild so far.
Our practices is to clone existing cube metadata as new one and add
extra measure/dimension or make changes, then build it.
Once new one ready, disable old one.
Hope this will help you.
Thanks.
Luke
Best Rega
Sure, we will try out refresh
What do you suggest in case there are some changes in the schema / extra
measures etc

Abhilash
