Not sure if i understood your suggestion correctly, a keyspace notif doesn't contain any info about the fields changed. Eg: __keyspace@0__:mykey del.
So, even if the lld_syncd logic was modified to send only one notif instead of mutiple. That'll be captured by this method. The actual logic of fetching the fv-pairs is in the downstream methods.

Thanks for clarify. I see the flow is implemented inside this file, instead of using a library. Sorry for misleading.
