Roman Kondakov commented on IGNITE-13022:
-----------------------------------------
We also need to check that it works for {{BETWEEN}} clause. As well as it
works in the presence of filters over several tables.
> Calcite integration. Merge index conditions for the same field.

> Key: IGNITE-13022
> URL: https://issues.apache.org/jira/browse/IGNITE-13022
> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Reporter: Roman Kondakov
> Priority: Major
>
> Index scans should be able to merge index conditions. For example query
> {code:java}
> SELECT * FROM tbl WHERE a<5 AND a<10
> {code}
> should be reduced to
>
> {code:java}
> SELECT * FROM tbl WHERE a<5
> {code}
> Parameters should be handled in a more tricky way:
> {code:java}
> SELECT * FROM tbl WHERE a<?1 AND a<?2
> {code}
> can be rewritten as
> {code:java}
> SELECT * FROM tbl WHERE a<MIN(?1, ?2){code}
> where the expression {{MIN(?1, ?2)}} should be evaluated right before the
> execution when parameters are known.
