java - 监听 Cassandra Datastore 的变化？

Question

我想知道是否可以向 Cassandra 添加一个监听器来获取表和更改条目的主键？如果有这样的机制就好了。

检查 Cassandra 文档我只发现将 StateListener(s) 添加到 Cluster 实例。

有谁知道如何在不破解 Cassandras 数据存储或封装驱动程序的情况下自行完成此操作？

"In databases, change data capture (CDC) is a set of software designpatterns used to determine (and track) the data that has changed sothat action can be taken using the changed data. Also, Change datacapture (CDC) is an approach to data integration that is based on theidentification, capture and delivery of the changes made to enterprisedata sources."-Wikipedia

As Cassandra is increasingly being used as the Source of Record (SoR)for mission critical data in large enterprises, it is increasinglybeing called upon to act as the central hub of traffic and data flowto other systems. In order to try to address the general need, we,propose implementing a simple data logging mechanism to enableper-table CDC patterns.
