SerializableTableWithSize

java.lang.Object
- org.apache.iceberg.SerializableTable
- - org.apache.iceberg.spark.source.SerializableTableWithSize

All Implemented Interfaces:

java.io.Serializable, Table, org.apache.spark.util.KnownSizeEstimation
```
public class SerializableTableWithSize
extends SerializableTable
implements org.apache.spark.util.KnownSizeEstimation
```
This class provides a serializable table with a known size estimate. Spark calls its SizeEstimator class when broadcasting variables and this can be an expensive operation, so providing a known size estimate allows that operation to be skipped.
