Class AsyncCalcSplitRule

java.lang.Object

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

public class AsyncCalcSplitRule
extends Object

Defines split rules for async calc nodes. These largely exist to isolate and simplify the calls to the async function from other calc operations, so that the operator can handle just that functionality.

Nested Class Summary

Nested Classes

Modifier and Type	Class	Description
static class	AsyncCalcSplitRule.AsyncCalcSplitNestedRule	Splits nested call <- asyncCall chains so that nothing is immediately waiting on an async call in a single calc.
static class	AsyncCalcSplitRule.AsyncCalcSplitOnePerCalcRule	Splits async calls if there are multiple across projections, so that there's one per calc.
static class	AsyncCalcSplitRule.AsyncRemoteCalcCallFinder	An Async implementation of RemoteCalcCallFinder which finds uses of AsyncScalarFunction.
