Concurrent builds for indexes on partitioned tables are currently not
|
||||||
|
supported. However, you may concurrently build the index on each
|
||||||
|
partition individually and then finally create the partitioned index
|
||||||
|
non-concurrently in order to reduce the time where writes to the
|
||||||
|
partitioned table will be locked out. In this case, building the
|
||||||
|
partitioned index is a metadata only operation.
