| TezParallelismEstimator |
| 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.
