All Implemented Interfaces:

Serializable, org.apache.flink.api.common.functions.FilterFunction<org.apache.flink.table.data.RowData>, org.apache.flink.api.common.functions.Function
```
public class DropUpdateBeforeFunction
extends Object
implements org.apache.flink.api.common.functions.FilterFunction<org.apache.flink.table.data.RowData>
```
A function drops only rows with RowKind.UPDATE_BEFORE changelog kind. This is usually used as an optimization for the downstream operators that doesn't need the RowKind.UPDATE_BEFORE messages, but the upstream operator can't drop it by itself.
