Class AsyncCalcSplitRule.AsyncCalcSplitNestedRule

java.lang.Object

RemoteCalcSplitRuleBase<java.lang.Void>

org.apache.flink.table.planner.plan.rules.logical.AsyncCalcSplitRule.AsyncCalcSplitNestedRule

Enclosing class:

AsyncCalcSplitRule

public static class AsyncCalcSplitRule.AsyncCalcSplitNestedRule
extends RemoteCalcSplitRuleBase<java.lang.Void>

Splits nested call <- asyncCall chains so that nothing is immediately waiting on an async call in a single calc.

For Example: Calc(select=[syncCall(asyncCall()]) -> Source

becomes

Calc(select=[syncCall(f0)]) -> AsyncCalc(select=[asyncCall() as f0]) -> Source
