Hi, Als one of your previous Mentors I’m still closely following the project. Still looking for ways to use it in my day job.
Now I am thinking about, how to process manufacturing data. The problem is: In manufacturing a LOT of Data is produced. However, I would say the further away from the Source the data is, the less important most of it becomes. So, I am thinking of a tree-like structure where Most data is stored close to the leaves of the tree (The Manufacturing machinery), because this is where I would like to run predictive maintenance and optimization jobs and these usually require a lot of data in a fine granularity. Most of this data is however irrelevant for the higher levels on not needed in this granularity. But again, some data is important on higher levels (Like detecting patterns in production, problem scenarios etc.) this can probably go up until some Factory dashboard for management with just some KPIs and perhaps even company-wide over multiple Factories. Here I’m thinking that an IoTDB node or even a leaf-node-cluster could store all the data produced by leaf-nodes and only data that is requested from an upstream instance is replicated there (Or even just virtually replicated, so queries would be forwarded to the leaf-nodes). So, my question is: Does IoTDB support this sort of hierarchies? If not, is something like this planned? I do imagine, that doing this manually would be possible, where every branch of the tree is a separate IoTDB node or cluster and then custom written code replicates data based on queries. However I do imagine this should be a pretty universal concept and therefore everyone implementing that manually would be a waste of resources. If something like this was possible, I know someone who might be really interested in this. Chris
