ElasticSearch can store sequenced number data, which is really all that Kafka is doing, so I don't think it is fair to say it isn't related at all.

- allengeorge 11y agoSo can a RDBMS... But that doesn't mean that Kafka and databases are related. As multiple comments have stated above, Kafka is really a distributed message subsystem. Its core interface is a set of topics that one can publish to, and that consumers can read from (in other words, a pub-sub system). Kafka doesn't inspect the message payload at all. Elasticsearch is a unstructured (to some extent) document store that's optimized around document search. So at the very least, the payload is important when using Elasticsearch.
- manigandham 11y agoThat's like saying they all write data to disk so they're related. Elasticsearch is all about saving, inspecting, indexing and retrieving your data through a rich document-based model and search-optimized methods. ES might be able to do the same thing functionally because it operates at a higher level but ultimately will never scale or be as simple in access as Kafka.
