I'm just asking you to estimate the monetary value of a product that can find links between any two vertices of a complex graph in a good search time.
The volume of search data reaches hundreds of millions of records.
The product to be installed locally in the customer's database.

If desired, the product can be integrated with the Kafka server and with various cloud services. You can also work with it by supplying search data to my cloud service.
But for today, I only ask you to estimate the cost of the basic functionality.
