What is the recommendation for regular maintenance on LHC on XenApp 7.15?

We are running XenApp 7.15 on Windows 2016 sitting behind Storefront and Netscaler.

While finishing up the configuration, I am looking into the LHC.  In the past,(XenApp 6.5)  we had a scheduled task to run dsmaint compactdb/lb daily.  In reading, I see that the LHC is still present, but with the new architecture and Delivery controllers in reading it doesn't necessarily sound like this is a recommended maintenance item to do unless I plan to force an outage.  However; maybe I'm misinterpreting.  This is the article I'm reading, https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/manage-deployment/local-host-cache.html.

Any insight as to what you do in your farms?

Thanks

I don't know anything about database maintenance with XA7.xx.

but ... Why do you run compactdb/lb every day?

This only works with Access-based database and datastore is unavaileble this time?

Access-Db may be grown, because dynamic data is written and deleted many times.

SQL can handle this.  

If you see an LHC size >1,5 GB you should compact the LHC-DB. but the command is " compactdb /l hc"

Because LHC is SQL-based today too, there is no compact-job for this.

XenApp 6.5 is also using an external SQL Database.  However; I didn't set that one up, so might be left-over from before that.  

Thanks for the clarification.  I won't duplicate this step in the new environment.
