Unlikely to happen if there are still Java services running in that stack. For instance ElasticSearch/OpenSearch is good at what it does (which is full-text search) but pumping massive amounts of logs into it is never going to be a light solution. Solutions such as Loki which just index tags and dump the raw content into an object storage bucket are the cheapest, and I guess ClickHouse ends up somewhere in the middle between those two depending on how well you configure it to fit the data. Or vice versa how well you can configure the data to fit the technical solution.
