Question

How to I add a current timestamp (extra column) in the glue job so that the output data has an extra column. In this case:

Schema Source Table: Col1, Col2

Schema of Destination: Col1, Col2, Update_Date(Current Timestamp)

Answer 1

We do the following and works great without converting toDF()

datasource0 = glueContext.create_dynamic_frame.from_catalog(...)

from datetime import datetime
def AddProcessedTime(r):
    r["jobProcessedDateTime"] = datetime.today() #timestamp of when we ran this.
    return r

mapped_dyF = Map.apply(frame = datasource0, f = AddProcessedTime)
