High Performance Time-Series Database Design With QuestDB

In this talk we will explore the world of time series and unique set of problems time series present to the developers. We will discuss the engineering principles behind QuestDB's design, focusing on high performance. We will also explore how technical and economical constraints of cloud providers shape database architectures.

Some of the challenges we are going to touch on are:

  • Geographical data distribution with cloud-native replication
  • Simplifying data pipelines with HA writes
  • Data visualization with high-performance SQL extensions and window functions
  • Reducing cost of data ownership with database-native cold storage integration
  • Providing data scientists with scalable data access
  • Vectorized and multithreaded SQL execution
