[druid-user] Nested datasources

We are creating a data repository where users will upload various csv files. And it creates inconvenience by the fact that over time a huge number of data resources will be created with which it will be necessary to work. According to our idea, we will give each user one data resource, where new files will be added, i.e. data resource will be constantly replenished with new records and columns. We are also considering a variant with something like nested tables.
I would like to get advice from those who have implemented something like this.
Thanks in advance.


This might be a good starting point:


By any chance, is this related to your solution to your datasource log question from earlier this year?
