Chunwei Lei created CALCITE-4223: ------------------------------------ Summary: Introducing column statistics to RelOptTable Key: CALCITE-4223 URL: https://issues.apache.org/jira/browse/CALCITE-4223 Project: Calcite Issue Type: Improvement Reporter: Chunwei Lei
Many systems depend on column statistics to compute more accurate stats, such as NDV, average column size, and so on. It would be nice if Calcite can provide such an interface. Column statistics might include NDV, average/max column length, number of nulls, number of trues, number of falses and so on.
