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.
Having similar syntax to Ruby makes it easier to port Ruby code to Crystal (ex: digest-crc -> digest-crc.cr). The Crystal stdlib is very complete and they have a growing "shards" ecosystem, roughly the same age as Rust's https://crates.io or Nim's nimble. You should look into Crystal again.
