I am working on Yearly partition Maintenance script which is on 1 T Table with 5 Partition of around 200G. Table has several indexes like 5-6 and all are Global Index. Maintenance is doing exchange partition and then rebuilding index as Exchange Partition is making the index unusable and so taking lots of downtime due to critical and comman table. So it is taking lots of time as well as generating lots of Log due to Database in LOGGING Mode

So I modified the exchange partriton to incldued UPDATE Global Index clause and so it work much faster as only Partition is tocuhed and so both Time and Logs are reduced.

Now question is what is difference between Creating GLOBAL index vs GLOBAL Partitioned index and where GLOBAL index is preferred over the latter.
