spark-avro - Datetime formats
I am working on the ingestion of data from Source DB to HDFS in avro format.
using spark-avro Package, since there is known issue for the Timestamp columns,
is it possible to find out all of the columns dynamically during import which are Timestamp / date-time type and Cast into STRING?
I am planning to write generic process - hence cant hardcode the columns, instead want to make this logic dynamic.
any pointers?
