ZiLin Chen created CALCITE-4682: ----------------------------------- Summary: Cost of Operator limit may break cumulative cost calculation assumption Key: CALCITE-4682 URL: https://issues.apache.org/jira/browse/CALCITE-4682 Project: Calcite Issue Type: Improvement Components: core Reporter: ZiLin Chen
Any way calcite can provide to solve the problem about cost of limit operator? Limit operator can affect how the join below to choose specific algorithm by start up cost instead of cumulative cost. However volcano planner can only deal with the total cost, which works well in OLAP system, but OLTP system need some kind of cost model to solve this problem. -- This message was sent by Atlassian Jira (v8.3.4#803005)
