Can we have custom callback for configuration data

[sukesh9995]

Hi @michalvasko

module: test
+--rw leaf1
+--rw leaf2* [name]
+--rw name string
+--rw value1 string
+--rw value2 string

Is there any possiblity that when a get-config request comes client, can we register a callback so that we can send the custom data instead of the data stored in running database.

Hi @michalvasko,

Basically can we get a callback for configuration data, so that we can frame the rpc and reply.

That's typically not how sysrepo is used. What problem are you trying to solve this way, and what exactly are your requirements? Are you maybe syncing configs between multiple backends, etc?

No, this is not possible and should be avoided. Such a design is bypassing the design of NMDA and I am guessing replacing it with something similar. So, you should instead understand the difference between running and operational datastore and then perhaps set some operational datastore callback, if required. Read through the NMDA RFC and understand how it is implemented in sysrepo by reading its docs.
