I’m from Brazil and working in a bank account application and card processing. We need improve performance to get account balance. Actually we are using sql server and doing a sum to get balances. The idea is put the balances in a cache server using aerospike. We will have a thousands of writes and reads of each account balance. Increasing and decreasing the balance.
Many financial institutions use Aerospike in this manner. I wouldn’t set this up without the full support of the Aerospike folks though. It might be a good idea to reach out to them and see what they can work out for you, they can help advise design and support. https://www.aerospike.com/forms/contact-us/
