Class IndexCondition

java.lang.Object

org.apache.calcite.adapter.innodb.IndexCondition

public class IndexCondition
extends Object

Index condition.

Works in the following places:

• In InnodbFilterTranslator, it is the index condition to push down according to InnodbFilter by planner rule.
• In InnodbTableScan, it represents a full scan by a primary key or a secondary key.
• In code generation, it indicates the storage engine which index to use and the associated condition if present.
