I would suggest not to use anything just for sake of using, first read about Cassandra and based on your use case make wise decision. 我建议不要仅出于使用目的而使用任何东西，首先请阅读有关Cassandra的信息，并根据您的用例做出明智的决定。

Cassandra is eventual consistent, but for accounting system you need ACID properties, which is not supported by cassandra. Cassandra最终是一致的，但是对于会计系统，您需要ACID属性，cassandra不支持。 Also cassandra transactions are different from RDBMS transactions. Cassandra事务也不同于RDBMS事务。 It support row level & each partition atomicity. 它支持行级别和每个分区的原子性。 Consider if you need to transfer money from account A to B. which are part of two different partitions, it will be difficult to maintain consistency. 考虑是否需要将资金从帐户A转移到B。这是两个不同分区的一部分，因此很难保持一致性。
