There is an issue in task 3. The partitioned table created in task 1 (from `covid19_govt_response.oxford_policy_tracker` table ) and the `covid19_ecdc.covid_19_geographic_distribution_worldwide` do not have any overlapping dates as the partitioned table has an expiraton set for 90 days and the latest record in `covid19_ecdc.covid_19_geographic_distribution_worldwide` table is of "2020-12-14". I had to recreate the table without passing partition_expiration_days to clear the task.
