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 minimize downtime, you can consider configuring you app to use multiple database setup: with primary/replica DBs. Instead of switching maintenance mode on, you can switch to read-only mode. There's a gem called rails_failover that makes the set up easier.
