-------------------------------------
Summary: 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
Fix For: 3.0.0-alpha3
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.
