Everyone can contribute! Let's learn together in a weekly cafe ☕

We love to break things, make mistakes, debug, analyse, fix problems together. Live and unfiltered on Youtube.

Community members and thought leaders regularly join and share their projects and ideas.

"Everyone Can Contribute" is inspired by GitLab's mission.

1. Cafe: QuestDB: Introduction, Live Demo, AMA and Roadmap



  • QuestDB introduction, a high-performance Time Series Database
  • Live demo
  • Charts, clustering, memory management, scaling, roadmap


Enjoy the session!


QuestDB Demo Charts

  • Grid and chart views
    • Idea: Have PNG/PDF export
    • Embed charts into GitLab alerts and incidents
  • Code base: Java 11 primarily. C is only for IO.
  • Clustering with QuestDB
    • Column first ingestion and inserting simultaneously mechanism to be built
  • Roadmap for next year
    • Replication (for OSS)
    • Out of order. Currently the series needs to be inserted in order, this is good for historical metrics replay.
    • Roadmap on GitHub
  • Enterprise version
    • First year focus on OSS, Enterprise is planned at ~18 months
    • Pulsar as Open Core model.
    • Uses QuestDB as library.
    • Superlarge environments at scale.
    • UDP based replication for nodes closer together.
