kylin query problem

[仇同心 <qi...@jd.com>]

Kylin crew:

Kyliin source, on Kylin query execution process analysis, there are two questions:

1, kylin is how to use the complete SQL parsing of calcite, obtain the SQL context;
2, kylin, how to get the data from the pre-computed data and calculated.



OLAPToEnumerableConverter、OLAPEnumerator、OLAPTableScan When to call?


Thankas!

Hi Tongxin,

I think your question is too general to answer with 1 or 2 sentences; Since
Kylin's source code is public, suggest you clone source code and then play
it from your IDE, that would be a good start:
https://kylin.apache.org/development/dev_env.html
