There is no limit to the number of tags a Transmitter can consume or a Sparkplug edge node/device can encapsulate. Many users try to keep edge node tag counts below 100K to reduce Birth build times, message size on the wire and processing required on downstream consumers (e.g., typically Sparkplug host applications and processing required for Sparkplug Birth messages. ).

Configuration

Fewer Transmitters with dynamically discovered Sparkplug assets reduce the overall amount of configuration to manage and makes it very simple to add new edge nodes to existing Transmitters, but start up work per edge node will be done sequentially. If creating or managing many Transmitters at scale, consider using Transmission's scriptable configuration APIs.
