Summary: Calcite integration. indexCondition refactoring
Key: IGNITE-14034
URL:
https://issues.apache.org/jira/browse/IGNITE-14034 Project: Ignite
Issue Type: Improvement
Components: sql
Reporter: Konstantin Orlov
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
