No description available [API reference]

Instructions

Apache Druid JDBC from Power BI, SQL Server Linked Server via ZappySys Data Gateway, Crystal Reports, SSRS, Azure Data Factory, and other ODBC tools.

  1. Use the Router or Broker host. Default SQL Avatica path is /druid/v2/sql/avatica/ on port 8888.
  2. If the cluster uses basic auth, fill user and password from the Druid coordinator.
  3. Prefer HTTPS only when TLS is terminated on that endpoint (see Druid SQL JDBC docs).
  4. Finish the wizard. Then click Test Connection on the DSN Main UI (the wizard does not run Test Connection).
  5. Done. You can query from C#, Python, PowerShell, and ODBC apps.
