The data doesn't have to be the content of user's notes. Think of all the metadata they're likely collecting per user/notebook/interaction – the data's likely useful for things like flagging security events, calculating the graph of interconnected notes, indexing hashed content for search (or AI embeddings?) ... these are just a few use-cases that come to mind from the top of my head.
Of which security and stability seems like the only reasonable use cases. Indexing content for search globally? Embeddings? They just can't help themselves, can they? All that juicy data, can't possibly leave it alone.
Great, you build only store and retrieve functionality. How:
1. Do you identify which types of content your users use the most?
2. Do you find users who are abusing your system?
3. Do you load and process data (even on a customer by customer basis) to fine tune models for the QA service that you offer as an optional upgrade? Especially when there could be gigabytes of data for a single customer
4. Identify corrupt data caused by a bug in your code that saves data to the db? You're not doing a full table scan over hundreds of billions of records across almost 500 logical shares in your production fleet
These are just the examples I came up with off the dome. The job of the business is to operate on the data. If you can't even query it, you can't operate on it. Running a business is far more than just being a dumb CRUD API.
a database, obviously, but are you really storing metrics and logs next to customer data in the same database, or did you skip over the part where I used the word “main”?
