Stream ExecNode which will drop the UPDATE_BEFORE messages. This is usually used as an optimization for the downstream operators that doesn't need the UPDATE_BEFORE messages, but the upstream operator can't drop it by itself (e.g. the source).

从类复制的说明: ExecNodeBase

Internal method, translates this node into a Flink operator.

指定者:

translateToPlanInternal 在类中 ExecNodeBase<org.apache.flink.table.data.RowData>

参数:

planner - The planner.

config - per-ExecNode configuration that contains the merged configuration from various layers which all the nodes implementing this method should use, instead of retrieving configuration from the planner. For more details check ExecNodeConfig.
