AdaptiveRulesHolder¶

AdaptiveRulesHolder holds the user-defined adaptive query rules for a SessionState.

The user-defined AQE rules are defined using SparkSessionExtensions injections:

• injectQueryStagePrepRule
• injectRuntimeOptimizerRule
• injectQueryStageOptimizerRule
• injectQueryPostPlannerStrategyRule

Creating Instance¶

AdaptiveRulesHolder takes the following to be created:

• Adaptive Query Stage Preparation Rules
• Adaptive Query Execution Runtime Optimizer Rules
• Adaptive Query Stage Optimizer Rules
• Adaptive Query Post Planner Strategy Rules

AdaptiveRulesHolder is created when:

• BaseSessionStateBuilder is requested for the adaptive rules
