OpenSearch, Vespa or ClickHouse: Building a Future-Proof Serving Layer

I have been working with Elasticsearch since its dawn, started over 10 years ago with version 0.12, and saw Elasticsearch becoming the de-facto standard technology for search, monitoring and log analytics. Today, OpenSearch (fka Elasticsearch) is widely used as a serving layer for websites and applications; for workloads of search, faceting, simple analytics, and more. Like every technology, OpenSearch has its own shortcomings you have to avoid to implement it successfully. As new modern technologies emerge, they may be more suited for some use-cases then good old Elasticsearch / OpenSearch. This session is about two of those technologies I consider the most prominent – ClickHouse and Vespa. In this talk we will walk through the common use-cases where Elasticsearch is used, give a quick technical introduction to Vespa and ClickHouse, and discuss the use-cases they excel in, and when you should consider. And of course - their shortcomings as well.
