handleWriteOperationV2(writeOperation: WriteOperationV2): Unit
Transforms the write operation and executes it.
Transforms the write operation and executes it.
The input write operation contains a reference to the input plan and transforms it to the corresponding logical plan. Afterwards, creates the DataFrameWriter and translates the parameters of the WriteOperation into the corresponding methods calls.

def
transformExpression(exp: Expression): Expression
Transforms an input protobuf expression into the Catalyst expression.
Transforms an input protobuf expression into the Catalyst expression. This is usually not called directly. Typically the planner will traverse the expressions automatically, only plugins are expected to manually perform expression transformations.
- exp
the input expression
- returns
Catalyst expression
