bufferInput(org.apache.flink.table.runtime.types.CRow input)
Buffers the specified input, it will be used to construct the operator result together with
the user-defined function execution result.

open()
This method is called immediately before any elements are processed, it should contain the
operator's initialization logic, e.g.
