当表通过INSERT或UPDATE查询更改时，cassandra中是否有发送通知的机制？ [英] Is there any mechanism in cassandra that sends notification when table is changed through INSERT or UPDATE query?

问题描述

我是Cassandra的新手，我想知道cassandra支持任何通过INSERT / UPDATE查询更改某些表时将发送通知的机制，以及任何游标通过结果进行迭代的机制。

I am new to Cassandra and I would like to know does cassandra support any mechanism which will send notification when some table is changed through INSERT/UPDATE query and any mechanism like cursor to iterate through results.
