@ralala - would love to hear your feedback once tried crate (jodok@crate.io). we've been working directly with kyle on the issues discovered. the current state of our work is documented on our website: https://crate.io/docs/scale/resilience/
Thankfully, for most use-cases, if you our follow best practices, you are extremely unlikely to experience resiliency issues with CrateDB.
I rember reading a blog post about crate facing data loss in some cases:

Is this still an issue?
