Class | Description |
---|---|
AccumulatorOptimizer |
A visitor to optimize plans that determines if a vertex plan can run in
accumulative mode.
|
CombinerOptimizer |
Optimize tez plans to use the combiner where possible.
|
LoaderProcessor | |
MultiQueryOptimizerTez | |
NoopFilterRemover |
For historical reasons splits will always produce filters that pass
everything through unchanged.
|
ParallelismSetter | |
SecondaryKeyOptimizerTez | |
TezEstimatedParallelismClearer | |
TezOperDependencyParallelismEstimator |
Estimate the parallelism of the vertex using:
1.
|
TezOperDependencyParallelismEstimator.TezParallelismFactorVisitor | |
UnionOptimizer |
Optimizes union by removing the intermediate union vertex and making the
successor get input from the predecessor vertices directly using VertexGroup.
