I have a table, each day has 5 million rows. At any given day i need to retain only prior 7days of
data. The data volume is huge to purge with a delete. So i intend to drop partitions / truncate
partitions that do not fall in the prior 7 day bucket.

Today being June 4th; i have to retain prior 7 days ; that is data from May 28 onwards.

If date was June 5th i have to retain prior 7 days ; that is data from May 29 onwards.And so on..

Since the partition key changes; how can i define this kind of partition?

Hope you can help, thanks
