DeltaInvariantCheckerStrategy Execution Planning Strategy
DeltaInvariantCheckerStrategy is a
SparkStrategy (Spark SQL) to plan a DeltaInvariantChecker unary logical operator (with constraints attached) into a DeltaInvariantCheckerExec for execution.
DeltaInvariantCheckerStrategy does not seem to be used at all.
DeltaInvariantCheckerStrategy is a Scala object and takes no input arguments to be created.
plan: LogicalPlan): Seq[SparkPlan]
apply is part of the
SparkStrategy (Spark SQL) abstraction.
For a given DeltaInvariantChecker unary logical operator with constraints attached,
apply creates a DeltaInvariantCheckerExec unary physical operator. Otherwise,
apply does nothing (noop).
