IBM® Informix® 12.10

Parallel user-defined routines

If a query contains a user-defined routine (UDR) in an expression, the database server can execute a query in parallel when you turn on PDQ.

The database server can perform the following parallel operations if the UDR is written and registered appropriately:
  • Parallel scans
  • Parallel comparisons with the UDR

For more information about how to enable parallel execution of UDRs, see Parallel UDRs.
