Adding Support for OpenTelemetry Context Propagation

OpenTelemetry is a tool for observing performance, helping to track and monitor data requests in distributed systems. Databend Query now has built-in support for OpenTelemetry context propagation, enabling better integration into existing monitoring systems and facilitating developers to track and analyze the flow of queries throughout the system.

If you're interested, please read the materials below to learn how to implement distributed tracing with the Databend Go Driver.


We have also made these improvements to Databend that we hope you will find helpful:

  • Added support for GEO functions st_makeline and st_geometryfromewkb.
  • Added support for refreshing inverted indexes after data changes, including synchronous and asynchronous modes.
  • Added time travel and specifying offsets for STREAM.
  • Read the documentation Docs | Access Control to understand access control in Databend.

What's Up Next

We're always open to cutting-edge technologies and innovative ideas. You're more than welcome to join the community and bring them to Databend.

Adding Support for Query Forwarding

Databend plans to support query forwarding, mainly for the following two benefits:

  • Flexible Routing: Avoids the necessity to route queries strictly to their origin node.
  • Statelessness: Similar to k8s deployments, the system doesn't require stateful management.
