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.
