In addition, the SPD Engine supports parallel index creation so that indexing large
data sets is not time-consuming.
The SPD Engine decomposes data set Append or Insert operations into a set of steps
that can be performed in parallel. The level of parallelism depends on the number
of indexes present in the data set. The more indexes you have, the greater the exploitation
of parallelism during index creation. However, index creation requires utility file
space and memory resources.
Note: You cannot create an index
or composite index on a variable if the variable name contains any
of the following special characters (even with the VALIDMEMNAME=EXTEND
option):
" * | \ : / < > ? - .
