Exchange Partition with "update all indexes" for a Global Index
Hi
There is a test table with range partition. There is an global index on this table. The global index is huge - about 200 GB.
When I set "alter table exchange partition part_1... update all indexes" this index is going to rebuild.
The question is Database is reading all index's segments and rebuilding them entirely or Database is reading only index data corresponding moving partiotion (not all index's segments).
From this point if I need to finish "exchange partition"(online) quickly Should I use smaller interval for range?
Thank you in advance,
Greg
