-------------------------------------
Assignee: Taras Ledkov
> Change the index cost model
> ---------------------------
>
> Key: IGNITE-14927
> URL: https://issues.apache.org/jira/browse/IGNITE-14927
> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Reporter: Taras Ledkov
> Assignee: Taras Ledkov
> Priority: Major
>
> Current cost model of the index is designed for 2.x indexes where IndexScan
> is cheaper than TableScan because index storage uses direct link to data
> pages.
> At the Ignite 3.0 index uses a primary key as the reference to the data row.
> So additional lookup by the PK is required.
