Hi Prabhat, I am one of the maintainers at SigNoz. Nice to see OpenObserve's belief that the future of Observability should be OpenSource. We chose clickhouse rather than building a database as it takes multi-year effort to move a db to maturity and clickhouse has been battle-tested at Yandex, Uber and Cloudflare. Clickhouse also provides native integration with s3 and other blob storages. Our users have been using disk as hot storage for a week and moving the data to s3 after that. Tiered storage is really cool in terms of query performance.

We have also seen logs data of our users at a compression ratio of 30x/40x. We have published a logs benchmark (https://github.com/SigNoz/logs-benchmark) where the data is very high-cardinal (causing a compression factor of only 2.5x). Would love to see how does OpenObserve perform in that dataset someday.

Wishing you best for the journey ahead.
