There will be 10 millions rows. After the index metadata is created we run an UPSERT SELECT (with a SCN at which the data table was resolved) to create index rows for all existing data rows. Any new rows that are written to the data table after the index metadata is created will be written to the index by incremental index maintenance (since when we resolve the data table we will see the newly created index).
