---------------------------------------
Summary: Calcite integration. Secondary indexes support.
Key: IGNITE-12715
URL: https://issues.apache.org/jira/browse/IGNITE-12715
Project: Ignite
Issue Type: New Feature
Components: sql
Reporter: Roman Kondakov
Secondary indexes should be supported by Calcite-based engine as well as they
supported by the legacy H2 engine. At first we can use the old engine for
indexes maintenance (building, updating, etc). In this case Calcite engine will
only use indexes metadata for query planning and index scans for query
execution. On the next iteration we need to eliminate the old engine usage.
Approximate plan for indexes support implementation:
# Add indexes to schema and set up all schema listeners.
# Add Collation to planner's output trait set and check if generated plan is
properly chosen in accordance to index sort direction.
# Implement index scans with filtering
# Add Sort node to exec.
