Maximum Number of Hash, Join, and Secondary Indexes Definable Per Data or Join Index Table

Up to 32 secondary, hash, and join indexes can be defined for one user data base table. Each multicolumn NUSI defined with an ORDER BY clause counts as two consecutive indexes in this calculation (see “Why Consecutive Indexes Are Important For Value‑Ordered NUSIs” on page 336).

Permitting all secondary index operations for one table to be performed at the same time allows the action to be treated as a single transaction; that is, either all of the indexes are created, or none of them are created.
