All Superinterfaces:

org.apache.beam.vendor.calcite.v1_40_0.org.apache.calcite.rel.metadata.Metadata
```
public interface NodeStatsMetadata
extends org.apache.beam.vendor.calcite.v1_40_0.org.apache.calcite.rel.metadata.Metadata
```
This is a metadata used for row count and rate estimation. It extends Calcite's Metadata interface so that we can use MetadataQuery to get our own estimates.
