Java has been fine for infrastructure projects. There is so much out there that relies on things like elasticsearch, Kafka, or any aws service. Heck even the columnar dbs like pinot and Druid are most likely more used than clickhouse. C# is also fine for this, just way less popular. Recently ms put out https://github.com/microsoft/Garnet https://github.com/microsoft/Garnet when the redis debacle happened. The Apache project has helped put out quite a few large infra projects, most of them in Java (I don’t know why this is but assume they have lots of resources to help with that, and also that people don’t like debugging memory crashes). Ms has just been not the greatest collaborators with their open source community. A lot of the time it seems like they want to do the initial foundation, then leave “drawing the rest of the owl” to the community, which ends with lots of partially functional things. GUI frameworks, f# tooling, drivers for commonly used critical infra. At the same time, people get upset when ms tries to build a better version of an existing open source project, so there’s no winning. They’ve just put themselves in such a poor spot.
