英文:
Should I use Elassandra instead of Cassandra to be able to use Elasticsearch?
问题
我正试图将我的Cassandra数据库与Elasticsearch集成，但似乎之前的DataStax连接器已被弃用，唯一的方法是使用Elassandra？
我想确保Elassandra是否是Cassandra的可靠替代品，是否没有简单的方法可以使用Cassandra + Elasticsearch？
PS：我在我的Cassandra数据库中没有任何先前的数据，如果有一种简单的方法可以从头开始索引数据，并通过Elasticsearch使用这些索引，那对我来说是一个好选择。
英文:
I am trying to integrate my Cassandra database with Elastic search but it seems the previous DataStax connector is deprecated and the only way of doing this is using Elassandra?
I want to make sure if Elassandra is a reliable alternative for Cassandra and there is not an easy way of using Cassandra + Elasticsearch?
PS: I don't have any previous data in my Cassandra db and if there is an easy way I can index data from the beginning and use these indexes by Elasticsearch this is a good option for me.

根据数据写入和在Elasticsearch中显示之间的延迟，我会考虑使用Apache Cassandra的CDC，它将数据插入/变更推送到Apache Pulsar主题，然后可以配置为将数据下沉到Elasticsearch或其他数据消费者。
这具有每个组件的单一责任的优势，并允许Cassandra和Elasticsearch独立扩展。
英文:
Depending on the latency between when data is written and when you need it to appear in elastic search, I would consider using CDC for Apache Cassandra, which will push data insertions / mutations onto an Apache Pulsar topic, this can then be configured to sink to Elastic / any other consumers of the data.
This has the advantage of single responsibility for each component and allows the Cassandra and elastic to scale independently of each other.
