QuestDB has relational data model supporting larger range of data types. We use SQL for all queries, have SQL optimiser and provide useful error reporting. All accessible over both HTTP and PostgreSQL wire. From our testing we are considerably faster to ingest data than Influx. We are faster for most queries and use much less CPU to achieve that. We have not tested with Prometheus or Graphite yet. On other hand we do not have high availability yet - this is on roadmap for next year.
