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.
To handle database migrations (changes to its structure) you write them and they are loaded on initialization. This is typically handled by an ORM or a framework though. I found this tool (phinx), which seems to be framework-agnostic.
