Hi all, I am currently thinking, if it wouldn’t be a good idea to build something like an open-source Historian based on PLC4X and IoTDB.
For those of you, who don’t know what a Historian is. In the manufacturing industry they have these extremely expensive servers (usually you buy them as a bundle of hard- and software). These servers are nothing else than a really crappy and brutally expensive Database for storing Time-Series data. The thing is most commercial products are currently really having trouble to keep up with the increasing amount of Data being sent. So instead of suggesting building an Historian at each customer’s site, I thought: Perhaps a ready-to-use solution based on open-source would be a good idea. Not 100% sure where I’d locate such an initiative, but I would tend to see it more on the Database side. I think IoTDB would be the perfect storage system, all we seem to need is some sort of rest-interface that matches the industry standards for querying the information and on the other side something like PLC4X to fill the database.
