Above link did not mention how to resolve/fix. Did I miss anything?

Sure I will be removing one

yeah I was setting up 'weekly' partitions, with rotation of dropping old & creating new partitions.
My DB ('event' table in the topic chain) has around 500Million of records and get add new records 2.5M avg. per day, when I query the DB based on datetime, execution completion is taking weeks.
To make query execution fast and for good performance decided to go with 'weekly' partitions.
