FAQ

• I get an error when adding a new data source: If you're running locally the host should be host.docker.internal. The user should be postgres and then your database name.
• I want to migrate my redash configuration (queries, etc) to another setup. The easiest way is to simply do a dump of the whole postgres database and instead of running docker-compose run --rm server create_db on the new setup, restore the backup on the first run. If that's not possible and you find yourself migrating data only you might need to:
  • Migrate a data-only pg_dump into the new setup
  • On the new setup, delete the data sources you have (which includes deleting query_results and setting null values to data_source_id across multiple tables)
  • Add a new data source on the dashboard
  • Update back all the columns you set to null to the new data source
  • Go back to the old setup and dump only the query_results table.
  • Back on the new setup, create a dummy data source with insert into data_sources (id,org_id,name,type,encrypted_options,queue_name, scheduled_queue_name, created_at) values (<id-of-the-data-source-deleted>,1,'a',1,'','','',now());
  • Restore the data only dump of query_results into the new database
  • Update all query_results to point to the correct source created through the dashboard
  • Delete the dummy data_source
