Does Ignition gateway without historian module has limited storage like Ignition Edge?
It does no history at all in that case, but you can script data storage and use named queries to retrieve such custom history for display.
That means it doesn’t have same functionality like Ignition Edge where it is having some local storage. Is that correct?
Because our idea is connect all the data sources at plant layer through Ignition gateway without Historian module and publish that to central Ignition on the cloud through Transmission module.
Please confirm.
Please note that we have data source from SQL db, we will not be able to use Ignition edge.

I recommend using Ignition's trial mode with several temporary virtual machines and/or docker containers to set up a minimal proof-of-concept.
