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.
Here's an example from a library I've used: https://github.com/sksamuel/elastic4s/blob/master/elastic4s-core/src/main/scala/com/sksamuel/elastic4s/Executor.scala. Then you can provide your own Executor implementation and it will be used instead of the FutureExecutor. You can check out the top level of that repo to see how much complexity this introduces.
