WORKFLOW ACTIONS

What you can configure.

Choose an action in the workflow builder, connect an account, and map its inputs. These actions are available in the catalog; your account access and a successful test determine whether they work for your setup.

Execute QuestDB query

Write

Run one SQL statement on the QuestDB server and return its rows, or the statement result.

Permissions and limits

Account permissions

  • The QuestDB user's rights for the statement

Operation limits

  • QuestDB's REST API has no bound parameters; map values into the SQL only from trusted steps.
  • SQL may change data. A lost answer is uncertain and never resent automatically.

A repeated request may repeat the external action. Review the previous result before retrying a write.

Insert QuestDB rows

Write

Append rows to an existing QuestDB table, all or nothing.

Permissions and limits

Account permissions

  • Insert into the table

Operation limits

  • Rows are imported as CSV through QuestDB's /imp endpoint into an existing table (create=false); values are converted to the table's column types.
  • A lost answer is uncertain and never resent automatically.

A repeated request may repeat the external action. Review the previous result before retrying a write.

SETUP

Start with a controlled test.

01Connect the intended account

Use the account and permissions required for your process. Review the connection check before configuring a workflow action.

02Review inputs and access

Select a listed operation and map its required inputs. Use test records and add a human approval before writes that need review.

03Confirm the result

Inspect step outputs and confirm the result in QuestDB. A saved workflow is not a completed provider action.
