Latency under 50-100ms to the database would be ideal, once we start adding 2-5 queries in a request, and time after this really starts to compound and add up.

Concurrency - the number of users initially will be 5-10 users but this will be expanding as we add more functionality and tools. But there maybe APIs and other integrations added over time.

Indexing - we will need a way to cache as indexing is a limitation. Some tables could be 100-thousands big with the need to join data.
