This seems like a pretty cool project!

Currently using Apache Skywalking myself, because it's reasonably simple to get up and running, as well as integrate with some of the more popular stacks: https://skywalking.apache.org/

I do wonder how ClickHouse (which Uptrace uses) would compare with something like ElasticSearch (which is used by Skywalking and some others) and how badly/well an attempt to use something like MariaDB/MySQL/PostgreSQL for a similar workload would actually go.

I mean, something like Matomo Analytics already uses a traditional RDBMS for storing its data, albeit it might be an order of magnitude or two off from the typical APM solution.

When compared with ElasticSearch, ClickHouse can handle the same amount data using 10x less resources and that is not an exaggeration. It is even worse with MariaDB/MySQL/PostgreSQL.

I guess ElasticSearch is still relevant when it comes to searching text, but ClickHouse is much faster when it comes to filtering and analyzing the data.

Give ClickHouse a try and you won't be disappointed.
