InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
Also, since 2.13.0, you get validation at runtime. But it depends on the context I'd say. For instance, for the test suite of doctrine/orm, the best solution is Attributes IMO. When you're doing DDD, XML sounds great!
