> Key: IGNITE-14034
> URL: https://issues.apache.org/jira/browse/IGNITE-14034
> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Reporter: Konstantin Orlov
> Priority: Major
> Labels: calcite2-required, calcite3-required
>
> Currently IndexCondition is quite cumbersome and hard to understand. The
> difference between bounds and conditions is unclear as well as unclear what
> should be used to estimate a selectivity and what should be used to estimate
> a self cost.
> Thus I suggest to change it in a follow way:
> * remove [lower|upper]Cond
> * bounds remains as is
> * self cost estimation of an AbstractIndex should be calculated with regard
> to bounds
> * selectivity should be calculated with regards to whole condition that is
> member of ProjectableFilterableTableScan
