[~Shaofengshi] great work!
[~yimingliu] looks like it's abbreviation for "true". If so it could be
confusing, why not just use "true"?

> Key: KYLIN-2424
> URL: https://issues.apache.org/jira/browse/KYLIN-2424
> Project: Kylin
> Issue Type: Improvement
> Components: Tools, Build and Test
> Reporter: Shaofeng SHI
> Assignee: Shaofeng SHI
> Fix For: v2.0.0

> Kylin's integration test is slow, especially the ITCombinationTest. Most of
> time are spent on H2 to execute the test queries. In a latest integration
> test, this test case take 90 minutes to finish.
> By checking H2's document, I think the main problem is the absence of index
> on the tables, while index is very important for a relational database's
> query performance. So when Kylin create the tables in H2, shoud create index
> on the columns that will be used in the queries, like the pk/fk, the
> filtering columns etc.
