Transaction in this case is not a database transaction, but a financial transaction (payment). Per payment, probably somewhere in the order of 50-100 database transactions (although Cassandra does not really have transactions of course, interpret this as read/write actions) will be performed in the course of its processing. So that is 1,875,000,000,000 database actions on busy days. Not a DBA, but for our purposes the scalability and availability of Cassandra works very well. |
