Connect

Opens a connection to QuestDB and returns a Client ID.

This node is also exposed as an AI Agent tool.

This node has 1 input port and 1 output port.

Common Properties​

Every node shares these.

  • Name — the node's display name on the canvas.
  • Color — the node's colour on the canvas.
  • Delay Before (sec) — wait this long before the node runs.
  • Delay After (sec) — wait this long after the node runs.
  • Continue On Error — carry on instead of failing the flow. Defaults to false.
info

When Continue On Error is true the error is not raised at all, so a Catch node will not see it either.
