- UI Extension 8128

Polling Interval The UI extension polls for some information on a background thread. It watches for changes to the list of attached databas...es, and it detects when you connect to MotherDuck. These checks take very little time to complete, so the default polling interval is short (284 milliseconds). You can configure it with a SQL command like: SET ui_polling_interval = 284; The environment...variable ui_polling_interval can also be used. Setting the polling interval to 0 will disable polling entirely. This is not recommended, as the list of... - https://man.mtool.work/duckdb/2.0/core_extensions/ui.html
