Hi,

Currently i am using list partitioning based on a status column to classify the data as ACTIVE and EXPIRED. And then the corresponding partitions are exported and then dropped from Prod.

The problem with this approach is the internal data movement when the status is marked as EXPIRED.

I went through the in-database archiving feature. I found it almost similar to what we are doing now.

Any advantage for us in mving to in-database archving from the current list partitioning (with reference partitioning for child tables)

You can combine In-Database Archiving with partitioning:

So it sounds like you could use this to do something similar to your current solution. Rows will still move between the partitions when you "delete" them though.

Would I move to it if you already have a working solution? Probably not. You'll have (significant?) rework for your application to move to it. The benefits would have to be large to outweigh this cost. Unless your current solution has other significant drawbacks, it'll take a while for In-Database Archiving to recoup the rework effort.

Would I consider it for a new table/application? Yes.

So the real question is:

What problems (other than "internal data movement") is the current solution causing you? And how do you expect In-Database Archiving to solve these?
