While Logstash and Fluentd are stable, mature, and tried solutions, there are also newer propositions in the unified logging layer space.
One of them is Vector, which aims to handle all of the observability data in a single tool. To differentiate from the competition, it focuses on performance and correctness. This is also reflected in the choice of technology. Vector uses Rust for the engine and Lua for scripting (as opposed to the custom domain-specific languages used by Logstash and Fluentd).
At the moment of writing, it hasn't yet reached a stable 1.0 version, so at this point, it shouldn't be considered production-ready.
