KairosDB is an open-source time-series database that uses ScyllaDB or Cassandra as a backend datastore. Time-series databases are vital for a wide variety of use cases, from vehicle tracking to industrial applications, and from security to IoT. Brian Hawkins of Proofpoint wrote KairosDB. He will share his vision and experience in managing time-series data. Faraday Future uses KairosDB on ScyllaDB as a time-series database, storing critical vehicle data in the cloud. Using RabbitMQ and Apache NiFi as an edge service, and Kafka as a message bus, the team built pipelines for smart diagnostics covering every vehicle in the fleet. ScyllaDB is the only storage point in the system.
