NimbostratusAre there limits to Data Group name length?
A simple question (or two) on data groups:
Are there any practical limits on the length of a key or value in a data group? I'm writing a rule using a string class against various long-ish URIs and the question came up. If I am using a long key name, are there any performance implications for lookups?
TIA,

dubdubI'm running into this question also - I will be checking URIs against AD group membership, and the list of groups authorized for a particular URI could be longish - maybe up to 2K characters? Will that work?
Thanks,

sol12112: The maximum size for a single string in a class or data group is 65,520 characters
https://support.f5.com/kb/en-us/solutions/public/12000/100/sol12112.html - dubdubHi Nitass,
I was thinking more specifically for an individual value in a string data group, but that solution makes it sound like the entire list is limited to 65K. If so, that may make things more interesting and I will have to break up my data group into multiple groups. On the other hand, I know that data groups support up to 100K entries - so does that mean the 65K limit is just on a single entry then?
Thanks,
Jen - nitassi understand 65k limit is on single string but data group size is limited on amount of memory.
- dubdubExcellent - 65K will more than cover what I need. Thanks, Nitass!!
