Telemetry

QuestDB sends anonymous telemetry data with information about usage which helps us improve the product over time. We do not collect any personally-identifying information, and we do not share any of this data with third parties.

telemetry.enabled​

  • Default: true
  • Reloadable: no

Enable or disable anonymous usage metrics collection.

telemetry.hide.tables​

  • Default: false
  • Reloadable: no

Hides telemetry tables from select * from tables() output. When enabled, telemetry tables will not be visible in the Web Console table view.

telemetry.queue.capacity​

  • Default: 512
  • Reloadable: no

Capacity of the internal telemetry queue, which is the gateway of all telemetry events. This queue capacity does not require tweaking.
