irule data class reference issues 9.4.x to 10.1

I have also made a few changes as the set data [findstr $item "|" 1 "\n"] also inserted a {} bracket.

 

 

You can use lindex to get the first list element instead of stripping the {}'s:

 

 

set data [lindex [findstr $item "|" 1 "\n"] 0]

 

 

The CMP compatibility page lists some suggestions for accessing classes in recent LTM versions:

The class command provides additional info on new ways to search datagroups:

I'm not aware of any performance benefit of using an external file as a source for a datagroup. Either way the datagroup contents are read from disk to memory upon config load.
