We are in the process of designing a Billing system for our product. Now we are in the look for the data store to be used. Elasticsearch is one we considered, do you recommend using it in a system like billing has some critical data. Our expected TPS is 500, that is 50 million records per day. Data retention period would be 1 year. summarization is done after one year. ---
